Q13's Most Wanted features Marysville murder cold case


MARYSVILLE — "Washington's Most Wanted," will be airing a segment, at 10:30 p.m., Feb. 26 and 27 on Q13 FOX, about the unsolved 1998 homicide of Marysville's Jennifer Brinkman.

Jennifer lived at 1909 Grove St. with her father, Michael Brinkman, who found her dead in their home on March 21, 1998. She was 19 years old.

Michael Brinkman and his girlfriend had left to go to Disneyland March 13, but Jennifer had decided to stay at home. This was the first time Jennifer had stayed at home alone for any substantial length of time. Michael reluctantly agreed to let her stay, considering it a test of her maturity. When Michael returned home March 21, he found Jennifer lying on the floor of her bedroom, and ran out into the street to flag down a Marysville Police officer.

Jennifer had moved to Marysville a few months prior to her murder, and didn't have any known close friends in Marysville. She was not going to school and not working at the time of the homicide. She was known to walk around Marysville, visiting various businesses and the library.

According to Marysville Police Detective Daniel Vinson, Jennifer was considered to have a minor developmental disability, with the mental capacity of a 13-year-old or 14-year-old. He added that she was very friendly and didn't hesitate to talk to strangers.

Vinson stated that, based on the evidence at the crime scene and the autopsy, it's believed there had been a brief struggle in the residence, and that Jennifer died of "chop wounds to the neck." An axe, believed to have caused the wounds, was recovered at the scene.

A great deal of potential evidence was collected from the crime scene. The Washington State Patrol crime lab was able to develop a DNA profile of an unknown man who may be involved in the homicide. As of today, nearly 12 years later, no match has ever been located for that DNA profile.

Marysville Police detectives received many tips and leads over the years. Several possible suspects have been identified during the investigation, but probable cause has not been developed for any of the possible suspects.

Vinson said that it's likely that the suspect or suspects have told one or more uninvolved people about the incident.

The Marysville Police Department remains confident that this case will be solved, and asks that anyone who might have any information contact Vinson at 360-363-8300 or
