Kyle Gene Deemer Killed His Ex-Wife

Kyle Gene Deemer

Friday afternoon Jessica Dawn Deemer, soon-to-be ex-wife to the gentleman pictured to the left, and her boyfriend Bryce Lee Mercer were headed to Mercer’s parent’s house when Kyle Gene Deemer ran them off the road on Highway 14 north in a rural part of Marshall County, Iowa. Their car was found in a ditch to the side of the road and the couple was found lying shot to death at the side of the road. Police received a call around 5:30pm informing them of the crash and a possible shooting and when police arrived they were told that the assailant had taken off in his silver pickup truck headed north.

Deemer was sighted and given chase by the Eldorado Police Department in
Hardin County. Eventually he went off the road and Deemer tried to flee
on foot. He was found and arrested later in the southern part of the
county, has been charged with two counts of first-degree murder and is
currently being held in the Marshall County Jail in Marshalltown.

Aside from the fact that two people are dead, one of the sadder aspects of this case as I understand it is that Jessica and Kyle also had a son who is now without a mother or father. From comments I have read (unsubstantiated as of right now) Kyle and Jessica were in the process of getting a divorce and something about it is what triggered Kyle’s reaction and subsequent murder of Jessica and Bryce. Regardless of the fact that they were not yet divorced there just is no sane reason in the world to have killed them. Deemer does seem to have a pretty extensive criminal history according to court records in the State of Iowa as well. That doesn’t necessarily signify that he would kill someone but it does show the progression in his criminal activity since he was around 20 years old. If there is any from his teenage years I couldn’t find it, but of course that stuff would be sealed anyway.
I haven’t found any kind of conclusive online information for any of them. Lot’s of links that may or may not be these folks but I’m not going to post them until I have more information.
Updates Below:


The Piersbacher Funeral Home web site has Jessica Luedtke Deemer’s obituary online. Her funeral is on Wednesday morning and the family is asking that any donations be made to the Ty Deemer Trust Fund. Here is the obituary in it’s entirety:
Jessica Dawn Luedtke Deemer of Waukee, Iowa formerly of Chariton, Iowa died Friday, October 17, 2008 near Marshalltown, Iowa at the age of 24. 
Jessica was born in Iowa City, Iowa on July 17, 1984 to Kevin and Lori (Greubel) Luedtke. She was raised on a farm near Chariton along with Jason, her brother, and Jamie, her sister. 
Jessica attended school at Russell Community School until her sophomore year and transferred to Chariton High School. She was a dedicated student and loved to learn. Jessica graduated salutatorian from Chariton High School in 2002. She had completed enough college courses and entered into Indian Hills Community College as a sophomore. In 2003 Jessica earned her Associates Degree and went on to further her education at Simpson College in Indianola. She earned her Bachelor of Science Degree in Business Marketing in 2005. 
Many memories were made during Jessica’s high school years as she worked her first job in the pumpkin fields with her family. She also worked at Double Dip for Annie and Becca where Jessica was a very dedicated and loved employee. At the time of her death Jessica was employed at Principal Financial in Des Moines as a compliance associate. 
Jessica had one son Ty Deemer age 6. Above all, her greatest joy was being Ty’s mom. She had a big heart and would sacrifice all for those she loved. Jessica was as beautiful on the inside as she was on the outside. 
Jessica was a genuine friend to all. She was a natural when it came to decorating. Whether it was a friend’s wedding cake or painting Ty’s room, her creativity was endless. She has always loved to exercise and recently began biking and running. This past year Jessica participated in RAGBRAI, the Dam to Dam Run, and Living History Farms Race. She enjoyed the challenge and was always the one encouraging her friends along the way.

Updated – Jessica Deemer Luedtke is to be interred on Wednesday morning. The update and obituary are at the end of the post.

Update 2 – Information on the funeral as well as the obituary for Bryce Mercer has also been added to the end of the post.

3 November 3rd 2008 – Kyle Deemer provided a written plea of Not Guilty
this past Friday in the shooting deaths of his estranged wife and her
boyfriend. The trial date has been set for January 13th but that may
have to be extended.

4 – Kyle Deemer’s trial was originally scheduled for last month
(January) but it has been rescheduled. He will be on trial for two
counts of first degree murder on August 25th. I guess since it’s such
an awful capital murder the attorneys felt that they needed more time
for discovery.

Update 5 9/23/09
– Last month the trial that was supposed to begin on August 25th was
rescheduled to November 16th. Along with having the trial rescheduled
there was to be a hearing last week for a motion requesting a change of
venue. I haven’t yet found whether the location change has been granted
or not but if it was that may also delay the trial even more.

Update VI 10/27/09 – As Rich noted in the comments the trial has been moved to Dakota City (Humboldt County). It is still scheduled to start on November 16th.

  1. Why do you use the term gentleman? That is an over used term. The title of gentleman is bestowed on a man for being courteous or gracious with a strong sense of honor. Not just any male is a gentleman, much less a man.
    This is no gentleman.

  2. You are damn sure right about that. I’ve been getting a lot of hate mail lately about calling people douchebags and scumbuckets so I figured a change would be nice. We all know what Kyle Deemer is so it doesn’t really matter what I call him.

  3. I still haven’t found a obituary for Bryce Mercer- Iowa should have the death penalty and this freak Kyle Deemer should be the first one in the chair— wait maybe he shouldn’t have been such a coward and should have shot himself instead of two people he was jealous and angry of

  4. I haven’t seen an obituary for him either. I read a newspaper report yesterday that said the funeral services were still pending at the Overton Funeral Home in Traer. Ahh, just found it here. I will also add it to the post as well. The viewing is today and the funeral on Friday.

  5. Iowa needs the death penality. Deemer deserves not to live not breathe another breath. He is a coward. When their was a restraining order out against him for Jessica, it just showed what a low life piece of crap he is. He did not care about little Ty to grow up with out his mommy. Obviously Jessica was leaving the low life who was not worth anything. He only knew how to abuse verbally, physically, and mentally. I hope he gets the shit kicked out of him in prision. He should of not been such a coward and turned the gun on himself, he did not care what life he took. Bryce was everything this piece of crap would never of dreamt about being. May he rot in hell.

  6. still haven’t found a obituary for Bryce Mercer- Iowa should have the death penalty and this freak Kyle Deemer should be the first one in the chair— wait maybe he shouldn’t have been such a coward

  7. I would like to know more about the restraining order. I agree captain douchebag (kyle) is a coward, but I want to see him rot in jail for life, with a friend named bubba that is in to guys

  8. Can you please tell me the where you are able to find the details about the guilty plea? I grew up with Kyle and was friend of Jessica’s. Obviously this whole situation has been disturbing and disgusting to me. Kyle is clearly not a boy I grew up with. His guilty plea is now requiring some very good friends of mine to face him and testify against him. I live far away now so the internet is really my only way to follow. I was unable to find those details anywhere else. Where did you get them?
    Chris A.

  9. I have known bryce my entire life and kyle should rot for taking such a great guy from the world.
    I always considered bryce my superman. he was the sweetest man a live and I hope karma kicks kyle’s butt for what he has done
