CONTRA COSTA COUNTY, Calif. –  The Kansas Bureau of Investigation (KBI) and the Ottawa County Sheriff’s Office, with the assistance of authorities in California, made an arrest connected to the August 12 shooting death of Matthew Schoshke in Ottawa County, according to a media release.

A family member discovered Schoshke’s body in his Tescott home. Schoshke’s Ford F150 pickup truck was also stolen from the scene.

Authorities attempted various investigative methods to locate the missing truck and on Tuesday, Aug. 22, information was received that led them to believe the victim’s truck may have been located in the city of Los Angeles.

KBI agents and Ottawa County Sheriff Keith Coleman traveled to California. They collected evidence from the abandoned truck and were also able to identify a suspect. On Friday evening, Aug. 25, a warrant for first degree murder was issued for the arrest of 34-year-old Robert Colson of Bucksport, Maine.

KBI agents, the Sheriff, and Los Angeles Police Department homicide detectives were working to locate Colson, but prior to identifying his location he was involved in an incident at approximately 11:30 p.m., Saturday, Aug. 25 in Martinez, Calif. During this incident he allegedly stabbed a person while aboard an Amtrak train. Colson was attempting to escape from the train when he was injured. He was then transported to a regional hospital for medical treatment. The Ottawa County Attorney will pursue extradition efforts following Colson’s release from the hospital.

The Ottawa County Attorney’s Office is expected to prosecute the case.
