Case Summary by Jody Ewing

On Tuesday evening, November 21, 1995 — just over one day before Thanksgiving — Martha “Marty” Erickson, 47, was murdered while on her way to a dance.

Her body was discovered the following day in Avon Lake’s shallow waters, and State Medical Examiner Thomas Bennett said Erickson had been beaten and stabbed. He estimated she probably died between 24 and 48 hours before her body was found.

Martha Erickson’s body was discovered along the edge of Avon Lake in Polk County.

Erickson enjoyed helping people fight their demons, and often attended Alcoholics Anonymous meetings even though she wasn’t an alcoholic. News of her murder shocked and saddened many who’d gotten to know her.

“She just wanted to help out,” Erickson’s oldest sister Laurie Rhiner said in a September 9, 2010 interview with WHO-TV Channel 13’s Aaron Brilbeck.

Rhiner said she remembers how excited her sister had been about the dance.

“That’s all she would talk about, was how much fun she was going to have … who she’s gonna see there and what they are going to talk about,” Rhiner recalled.

Iowa DCI Director John Quinn spoke with Channel 13 reporter Aaron Brilbeck in September 2010 about Martha Erickson’s unsolved case.

Police said the body offered few clues due to time spent in the water, and that they couldn’t even say for sure whether Erickson had been sexually assaulted.

“Anytime you have a body at a location, remote in that area — also with the body being submerged which causes destruction of physical evidence — what you have to do is go back and track down the subject’s time line and establish who it was that she was with,” Iowa Division of Criminal Investigation Director John Quinn told Brilbeck.

That task proved virtually impossible due to the people with whom Erickson associated.

“Some of the meetings, they only use first names and some of the people are unwilling to go ahead and discuss the incident and interactions with people,” Quinn explained. “So we did have some barriers to success.”

Laurie Rhiner says she copies with the pain of losing her sister through artwork.

Rhiner said the hurt never goes away, but one just has to learn to live with it. Rhiner copes with the pain through her art, and says her younger sister is the inspiration for much of it.

Still, there are thoughts that come back to haunt her.

“You start thinking, what were her last moments like?” she wondered. “And you get so sick to your stomach you start shaking because you weren’t there to help her.”

Rhiner said she’d always been there to protect her baby sister and keep her out of trouble, but this time, she wasn’t.

Two of Erickson’s acquaintenances also murdered, officials study connections

Susan Kersten

The week after Erickson’s death, Johnson County officials said they’d discovered Erickson was an acquaintance of Susan Kersten, an Iowa City woman whose severely burned body had been found two months earlier on September 24, 1995 in the charred remains of her car in a farm field southeast of Iowa City. Kersten, 38, died as a result of blows to her head suffered before the fire.

Erickson knew Kersten from a group both participated in, Johnson County Sheriff Robert Carpenter said in a Cedar Rapids Gazette article dated December 1, 1995. Carpenter said he didn’t know if the two were close friends, but that there appeared to be no link between the deaths.

Officials had interviewed Erickson in Des Moines shortly after Kersten’s death, along with a number of other acquaintances, Carpenter said, but the interviews were strictly routine.

Polk County Detective Dennis Marshall — who was in charge of Erickson’s murder investigation — said the fact that the two women knew each other was not high on the list of leads.

“Martha lived in Iowa City for a short time,” Marshall said, “But we’re concentrating on things here because of the leads we have. We’ll work the leads from the top down, and it’s one lead we’ll eventually cover.”

Marshall also confirmed that Erickson knew Steven Klein, the father of Kersten’s twin daughters, but reiterated that they only knew of their acquaintance and had no strong link between the two deaths.

Klein was arrested July 17, 2015 in Muscatine and charged with first-degree murder in Kersten’s nearly 20-year-old unsolved homicide. His trial, originally scheduled to begin Nov. 3, 2015, has been continued until spring 2016.

Just over one month after Erickson’s murder, someone shot 37-year-old Donna Lee Marshall in the head January 8, 1996, at her Iowa City trailer in the Bon Aire Mobile Home Lodge. Marshall knew both Kersten and Erickson, but the investigation into the acquaintance of all three women yielded nothing substantial, Johnson County Sheriff Carpenter told the Gazette in a story published May 12, 1996.

Carpenter said detectives and DCI agents were talking at least weekly on the cases to evaluate their progress.

    anyone remember the name of her boyfriend about that time they worked together at gas station on Ingersol

  2. This is very heart breaking.

  3. Aitch Lewis says:

    I think they have finally arrested the correct person for these 3 murders today. May god have mercy on their souls.

  4. Deb Rau says:

    Wow, all three woman knew each other and there is a male, Steve Klein that knew all of them? Did all three of these woman like to go to the dances? How did they know each other?

  5. Prayers for the family.

  6. TY Jody for posting this.. if ONLY someone would come forward.

  7. Beth McFall says:

    Wow….just awful…and how coincidental that 2 of her acquaintances were also murdered???

  8. Prayers with the family and friends. God bless.

  9. Michelle says:

    What is even stranger is that the man Steve Klein knew all three victims also??? Why has his life not been scrutinized to the fullest. I truly believe this man had something to do with all three murders.. That’s just my opinion and not a fact.. Too many coincidences for this not to be fully investigated even after 20 years!! Just a blatant judicial error on the police’s part. Then to give the kids to him after he is considered a suspect is mind boggling. The grandparents have not been able to be involved in their lives since the murder. If that doesn’t ring many alarm bells, I don’t what will.

  10. Lori Johnson says:

    Call me foolish, but 3 women, who knew each other, (no matter how long!) end up murdered and the police don’t find that odd or claim its just one of those things…?!

    My hinky meter just exploded. Unless we live in a parallel universe the linkage between these women must be investigated FULLY. Odd doesn’t even begin to explain this…

    • Laurie says:

      I had thought that same thing Lori but they said they did investigate it and found nothing. HMMMMMMMM..the case truly was a mess up.

    • Jordawn Williams says:

      I was thinking the exact same thing!! I’m sorry but there has to be a connect somewhere and probably with the man.

      My heart goes out to all the families… I hope you can soon find some closure!!!!

  11. Tammy says:

    Yes, Martha loved those dances! I will never forget, the first dance I went to, her telling me how beautiful I looked. It meant the world to me. I will never forget her.
