Murder on a weekend getaway

LOWER HERRING LAKE, MICHIGAN-- I’d been to this scenic part of northern Michigan many times over the years. Not as a reporter, but for vacations when my dad and I would catch salmon and trout from Lake Michigan. As a young man, I sailed with friends every summer on the same lake. For the last 10 years or so I’ve returned with my family from the east coast every other summer so that my kids can spend time with their cousins on the beautiful beaches here. The small water front towns that make up Benzie County stay busy in the summer but are not overrun with tourists. Saloons serve fried perch and planked whitefish, two local specialties. I very much like recharging my batteries here. It’s about the last place you’d expect to be following leads in a story about addiction, betrayal and ultimately it was alleged, murder.

And just like the small resort area seemed an unlikely crime scene, the accused killer and the victim seemed unlikely to ever be center stage in such a drama.  Mark and Florence Unger had crossed paths in college, years later dated and ultimately got married and had two sons. It seemed for a time they had it all, living in the very hip Detroit suburb of Huntington Woods. Mark was a sports reporter for a radio station before going into the mortgage business. Florence worked in retail, became a stay-at-home mom and ultimately went into the mortgage business as well.

Along the way though there were problems. Mark admits he got hooked on painkillers after a back injury. He battled alcohol and gambling habits as well. Mark eventually went into rehab, but it was all too much for Florence who finally filed for divorce. While there seemed to be no chance for reconciliation, Mark, Florence and their two young sons decided to take a fall weekend trip to their favorite spot in northern Michigan, a resort they’d visited for years called Watervale on the shores of Lower Herring Lake. The couple seemed to be getting along or at least tolerating each other as the family had dinner at one of their favorite restaurants.

Later that night they returned to their cottage. Mark says the boys started watching a DVD. Florence and Mark ended up on a boathouse deck overlooking the lake. What happened next is still in dispute, but ultimately it lead to Florence being face down in the lake and Mark charged with her murder.

Florence Unger was found in these waters.

A top prosecutor would face off against one of Michigan’s most respected criminal defense lawyers. Two families, once joined by a marriage were now deeply divided and two young boys were caught in the middle.

Tonight you’ll hear from virtually everyone involved in the case, from Mark Unger himself and from those who speak for Florence. As you’ll see, this was by no means an open and shut case. Consider this: when I was watching some of the closing arguments in the Benzie County court house, I ran into some reporters I’d known for years, who were also covering the case. Some of these folks I’d known for 20 years from back when I was a reporter in Detroit. I asked a couple of them who’d been in court everyday and had covered the case from the get-go to predict the out come. They were wrong.

Is it at all possible she could have rolled into the lake after the fall.  What time of nite was it so as to know how dark it was.  Also by the time we're adults, we usually resolve somewhat our fears such as the fear of the dark.  Also, had he been through rehab and done well as far as dealing with his issues before this situation.  Because he seemed to sound like he was aware that the "behaviors" after his addictions are the most predominant problems were the contributing factors as to the breakdown of the marriage.  Very important to the rehabilitation treatment.  Also, some personalities react to the "fight or flight" behaviors due to social upbringing.  I am a recovering addict of 15 years and have studied co-dependancy exstensively for years due to severe mental, physical, and sexual abuse.  I hear now that she could have bounced or rolled of the cement.  Where are the rest of the crime scene photos.
I find it odd that they would go away for a weekend after filing for divorce.  When I filed, a weekend getaway was totally out of any question.
too much reasonable doubt i mdon't buy the conviction. thhey fell for the hocus pocus from the dr. who had 2 timelines. noibdy knows what they would do under those times because very few have been
I just got a really gut wrenching feeling when I began to listen to the evidence.  Even before I knew the outcome I would swear on a stack of Bibles that he did it.  Just the simple mindedness of him alone told me volumes.  What a insult to everyone involved in the case!  Did Mark really think the world was going to fall for his assanine story. Mark belongs right where he is.  I hope he rot's in hell.

I just heard that Mark lost his parental rights, Amen, there is justice.
Interesting story. The real losers here are those 2 boys who will grow up without BOTH parents.  Real tragedy.
It seemed very strange that he did'nt help drag his wife's body from the water.  He also wanted custody under any circumstances- or so it seemed.  I think he did it.
My first question is "If she was afraid of the dark, why would she have gone down to the dock in the first place?".  If she indeed was afraid of the dark, maybe something startled her and cause her to fall over the railing, which I also believe she could have rolled off the cement platform.
It happened.  He deserved to be found guilty.  I saw. He pushed her over the edge.
It was an interesting show, thanks.
Everyone of these Dateline Specials that person has always been guilty.  There has never been any different ending even with all the drama.
What a horrible mistake by the jury!  There is nothing but reasonable doubt written all over this case.  I'm not saying he couldn't have done it but there is no proof.  This definitely does not make me feel confident in our judicial system or the morons that sit on the jury.
Obviously I wasn't there, but doubt was.
Remind me not to go to Lake Michigan for a vacation! I'm astounded that the D.A. took the case with virtually no concrete evidence whatsoever?!?!?
I beleive he is guilty according to the evidence given you usually don't go away when you a in the middle of a divorce he seems very guilty to me.
One thing that was not explained was why there was no DNA evidence.  Was it cold enough that they were wearing gloves and coats or something?
Where's the pool of blood on the concrete? If she spent any significant time on the landing there would be more blood. The defendent said that when he picked her up out of the water "blood went everywhere".

I'm not saying the man is innocent but there is certainly reasonable doubt.
THE EVIDENCE WAS DEFINITELY SHOWN BY THE PATHOLOGISTS.  THANK GOD THE TRUTH COMES OUT AND ANOTHER OJ DID NOT HAPPEN.
Not enough evidence to convect.
I beleive he is guilty according to the evidence given you usually don't go away when you a in the middle of a divorce he seems very guilty to me.
I was fascinated by the story. To me, the condition of the deck would have been too much questionable doubt. Also, why didn't the defendant know that the vedict was in? If you watched the defendant he was very moved during testimony, most of us aren't that good of actors.
I thought the same things as Diann from August GA but admit my first thought was "Someone's getting killed" when I heard they were going to a retreat for the weekend!  After watching the story, my husband and I both agree he seems innocent.  It is perfectly plausable for her to have fallen over, landed on her head/side and rolled off into the water.  Was she found in the location her husband had left her?  Maybe that is why he ran to straight to her...He went to where he'd last seen her.  I believe him - his story of having thought she was at a neighbors and not wanting to disturb her, giving space.  As for wanting to get his children home, I get that too as a mother of two young children.  I would want to get them back home, to familiar surroundings, home if someone horrible happened in our family.  Maybe a way of escaping reality a bit longer?  What a horrible thing, to be ripped from his children!  Indeed children grow out of deep fears.    
I could understand the defense's argument of Flo falling and rolling into the water had she actually either hit a surface which was on an incline into the water or even if they had tried to prove suicide and that she took a flying leap.  This was a woman who fell 12 feet down landing on a hard flat surface. The 2-3 cartwheel videos of the defense just seemed silly and unrealistic.  Bottom line - how did she get in the water?...It didn't seem like it would have taken acrobats.  
What about the best friend ---perhaps she called it off with him just prior to leaving for the weekend to try and put it back together and he followed and as we all know rebound not so good - he should have been suspect #2
At the end of the interview, when asked not once, but twice if he killed his wife, Mr. Unger stated both times "that he would never do anything to HURT his wife."  Not once did he answer the question of if he killed her.  That spoke volumes to me.  The evidence also favored the prosecution in my point of view.
I don't know whether he was guilty or innocent; only Markknows that .  What I do know is that NOONE should ever go to jail on circumstantial evidence.  Where was the proof.  It's a scary thought that someone can go to jail for life without any physical proof.  I think that's a serious flaw in the justice system. As for the piece of evidence concerning his running to the exact spot where she lay, He ran to the boat dock.  The same spot he went to whenever going to the water.  Why would he not have run naturally to the same spot he probably had a thousand times before.  Think about it.
I think he did it.  The fact that he failed to go to the Duncan's cabin after he went back out and didn't see her made me believe there was something missing to his story.  Why wouldn't you at least check to see if she was with them rather than going back to the cabin and going to bed.  There were too many unanswered questions.  He talked about not being capable of hurting her but he can go to bed and not know where she even was in the deep dark of the night.  He had to know she was scared of the dark also.  His story just doesn't add up.
When asked twice if he killed his wife, he said he would never hurt her, but never denied killing her
I live in Mich. and have followed this  story from the beginning. I do believe with all my heart that Mark Unger was guilty of killing his  wife. I was on a jury and helped  convict a man. I tell you, its not  easy for jurors to convict. They took a long time before finding him guilty. I believe they did what they thought was the  right  thing.
this was ruled a homicide almost immediately by the medical examiner. and never once did mark say WHO KILLED MY WIFE?
is there a book available on this story..?
email me with info if there is please..
I find it very "interesting" that Mark Unger, when asked by Chris Hansen, "Did you kill your wife?" could not say "No, I did not kill my wife."  He said twice when asked, "I wouldn't do anything to hurt my wife."  Hurt and kill are two different things.
I disagree with the verdict in this case.  Although they were on the outs, they would getaway for the sake of the children since that was a place they had gone to every year.  After all, it's all about the kids.  I believe the body would have rolled into the water and, even if it did not, who's to say she didn't attempt to get up and in dizziness fell in the water and drowned.  The deck was rotted and not within code......too many things which indicate I was a possible accident and not a murder.  No those children will grow up without both parents....
If you spend enough time in Northwest Lower Michigan even the most sane person will lose their mind. It is beautiful there, However it can be boring as hell.
I spent four years there, However I never tried to off my wife.
Reason #1-When you are going through a divorce, you do not go out of town together.
Reason #2-If you find your spouses body in the water after missing over night, an innocent person would drag the body out of the water and try to revive that person, especially if you loved them.
Re: "Murder on a Weekend Getaway". The forensic witness testified that the body "bounced" on the deck....  The juror said that she knew that bodies do not bounce.  Well I saw a fellow soldier fall from a telegraph pole and he did bounce about 4 feet straight up.  I saw another in combat that bounced a very long way when blown to the ground from a tower.  How much more did this juror (or others) not understand and then did not question before making up their preconcieved decision?  
I didn't see the whole story, was her body not found until morning?  Or did he find it shortly after he put the kids to bed?
With no physical evidence against Mark, and him passing a lie detector test, it would seem that the jurors would have gone with a "not guilty".  If things were as bad as commented by friends and family...then why would she go away on a weekend getaway?  Just doesn't make sense.  And as an adult I can't recall anyone I know that has a fear of the dark so intense that they won't go outdoors alone in darkness.
I have a hard time understanding why someone did not say that she could of falling off the deck and hit the ground and then tryed to get up and walk/stumbled into the water.
I always say you can tell so much from someone's behavior, he did not seem genuinely upset, as he would have if he had nothing to do with it.. if it were my spouse lying in the water they would have to drag me out with him,, I don't buy anything that he said.. why would she be out there alone and just happen to fall from the deck.. doesn't make any sense.. it just makes more sense that he is behind it.
Just looking at his face, especially those sniveling lips, made me mistrust him.  His character was definitely not upstanding.  He became addicted.  He did too many things that a good man would not do.  I think he did know or was suspicious about the affair his wife had with his best friend and wanted the ultimate punishment for his wife.  Many men cannot allow their girlfriends or wives to crush their egos or pride.  If they can't have the women, they want to be sure she doesn't go with anyone else.  It is quite common for men to kill their wives and girlfriends rather than let her go with another man.
Typical female lawyer praying on the emotions of an uneducated and backwoods jury.  All white, predominantly female jury.  Want some real facts; why don't you measure how far or high a body bounces from a fall of 15 feet or less, I'll bet you will find it bounces a couple of feet, easliy.  It wasn't the husband screwing some other woman, it was just he opposite, must explain something about the character of the woman who died.  Facts determine a case, not opinion.  Maybe she got what she deserved.
I find it interesting at the end when Mark was being questioned by Dateling.  He was asked "Did you kill your wife?"  His Reply:  I would never do anything to harm her, second "But did you Kill her?" I would never do anything to hurt or harm flo.  That along with not pulling her out of the water no matter how much blood, assuming she was with the neighbors...to many gaps.  I believe justice was served and Pray those little boys grow up in a stable home with both sets of Grandparents.  Let's remember Mark was found guilty, the parents, they too are victims.
Mr. Hansen  My gut feeling watching this report made me ask questions which I wonder if were ever considered. 1. could Flo, had hit her head, bleed and been knocked out, then later regain consciousness, and when attempting to stand again in a dizzy state fallen into the water. 2. did she have a cell phone with her and or this lover, where was he. Perhaps she stayed behind to call him.  3. when the couple was on the deck what was the topic of discussion.  To me the failure of the railing (as a builder) seems to be very strong evidence.  I discount the run to the site, as Mr. Unger knew where he last saw his wife and of course he would head to that spot.  I just hope that if a mistake was made that this gets a second look.
How could they convict a man with so much reasonable doubt?  It was clearly evident to me that he should run to the water right at the boat dock if that were the last place that he had seen his wife.  It made complete sense to me that he would want to just take his kids and run from that scene.  He had been through recovery and had accepted his role in the breakdown of the marriage.  He understood his demons.  Just doesn't make sense that he purposely would take the family on a trip for the sole reason to kill his wife.  And, when you are going through a divorce sometimes that is not necessarily what you want, so the trip would make sense.  Also, I'm only scared of the dark on occasion now.  Being at the lakeside with the night sky lights would not frighten me.  Having to continue a difficult conversation with my husband would need strength and taking a breather on the boat dock would not seem that frightening.  The boat dock needed many repairs and was rotting.  It was more likely a horrible accident. And a loving father has now gone to jail.
I live in Traverse City Mi- 15 minutes from where this happened. I visited the crime scene shortly after this happened. It seemed his story was a stretch at the time, and as the trial played out it became more and more obvious he was a guilty man who thought he got away with murder. Dateline did a great job doing a fair and balanced story. Thank you.
There is absolutely no way Flo would have stayed out on the deck alone while Mark went to put the kids to bed alone.  What would be the reason for that?  Especially being afraid of the dark.  What took them out on the deck in the first place was probably to speak of the divorce.  I am glad to see that justice was done.  This case shows that those who sit on the jury are not always morons as in the case with O.J.
One thing stuck in my head,the last question Chris asked Mark....did you kill your wife?  His answer was not no, instead he said "I would never hurt my wife."  Not to mention the fact that he said it 2x.  Another thought, if Mark did not know about his wife's affair, why would his best friend (Flo's lover) ask him if he minds him staying at their house?  They are best friends, why would he mind, unless he knew of the affair?
I feel he absolutely is guilty. He knew that she would be awarded full custody of the children. He is a egocentirc and spineless loser of a man. Now, thanks to his pure selfishness, those poor children are parentless!!! I just pray those children can find some happiness in there new lives.
If she was alive for an hour and a half, what did he do during this time. why did her husband wait that long to push her in the water.  my instinct tells me that they were both right.......  he found her thought she was dead and thinking people would think it was an accident cause it was......he pushed her in the water......but who am I , oh yeah a potential jurior.  I pray for the boys they truely are the victims.  
It certainly appears that he did it.  However, I feel that there IS reasonable doubt.  I don't think that the prosecution gave a 100% convincing argument.  I think he did it, but I would not have voted for a guilty verdict.
