Des Moines man charged with murder in stabbing death of elderly Auburn man

King County Prosecutors on Oct. 6 charged a Des Moines man with second-degree murder in the fatal stabbing of an elderly Auburn man.

Sheriff's deputies arrested 26-year-old Andrew Cory Lagerquist on Oct. 2 shortly after they responded to a 10:35 a.m. 911 call from a home in the 4800 block of South 288th Street on the West Hill.

Deputies found 75-year-old Don Marinoff inside his home in critical condition, bleeding from multiple stab wounds. Medics transported the mortally wounded man to Harborview Medical Center in Seattle, where he later died.

According to the statement of probable cause written by King County Sheriff's Detective Jon Holland, the King County Medical Examiner's autopsy found six stab wounds, three in the left side of Marinoff's abdomen, two in his right and left upper thigh and one on the back of his left hand.

According to the statement of probable cause, several people at the home that night saw Lagerquist stab Marinoff as the old man sat in his chair. Police have not found a motive for the crime, but one witness told investigators that Lagerquist and Marinoff had argued the night before. How they knew each other, the nature of their relationship and what they were arguing about is unclear.

Lagerquist fled the scene, but deputies soon captured him at a friend's house. According to the statement of probable cause, several people who saw Lagerquist after the stabbing told investigators he had been agitated and was sweating profusely and acting strangely.

According to the statement, Lagerquist told detectives he knew nothing about the stabbing and wasn't involved. Lagerquist, who has four felony convictions for robbery and firearm possession on his record, also told investigators he "would not go back to prison,"

According to the report, when Lagerquist learned during that 50-minute interview that a witness had identified him as the person who stabbed Marinoff, he became confrontational and had several profane emotional outbursts. According to the statement, he even threatened Holland with bodily harm. He did not confess.

Lagerquist's friends told police he is a known user of methamphetamine and PCP.

Prosecutors, citing Lagerquist's prior convictions, have asked for $1 million bail. Lagerquist sits in the King County Jail awaiting his Oct. 19 arraignment.
