King County prosecutors filed a second-degree murder charge against 46-year-old Michael Sean Thompson Friday in King County Superior Court.
Thompson remains held on $2 million bail in connection with the death of 49-year-old Daryl Ford, a homeless man.
The probable cause document implies that Thompson killed Ford at the low-income housing facility connected to Sound Mental Health where Thompson resided.
Though graphic details emerged about Ford's fatal injuries, the police report attached to the criminal charges lacked any clues about a possible motive or the circumstances leading up to Ford's death.
Thompson was already wanted for arrest at the time of Ford's death. He was to begin electronic home detention for a vehicle theft conviction months earlier but after he failed to arrange for his detention by his May 19 deadline, a warrant was issued for Thompson on May 22, the day Ford's body was found in a residential parking lot.
A woman living on South Austin Street saw a man that morning in her front yard loading clothes from a grocery cart into her garbage cans, according to the probable cause affidavit.
She told him to leave, so he removed the clothes from her bins and deposited the cart outside the home of a neighbor.
The woman suspected that a bundle of bedding contained a body, so she called her neighbor, who then called 911, reports say.
Police arrived and found two human feet sticking out of some blankets in the grocery cart, according to the affidavit. The feet were discolored and cold to the touch and the body was wrapped in blankets and tied with an electric cord.
Seattle Fire Department medics found multiple stab wounds on the body's upper back.
The autopsy indicated that the body, identified as belonging to Ford, had been stabbed more than 80 times, with stab wounds to his spinal cord, liver, both kidneys and both lungs.
The wounds to his spinal courd would have paralyzed Ford from the chest down had he survived, reports say.
He also suffered blunt force trauma to his head and stab wounds had chipped his skull, according to the affidavit.
Investigators recovered documents connected to South Mental Health, which had a housing facility a few blocks south of the site on South Kenyon Street. The documents also contained Thompson's name.
With Thompson's fingerprints recovered from the grocery cart, police arrested Thompson at his wife's house the night of May 23. There, Thompson admitted to seeing Ford a few days earlier and that they got high together, but then requested an attorney.
Detectives reviewed surveillance footage from the Kenyon House the night before and the morning of the discovery of Ford's body.
The video shows Thompson heading into his room late at night with a man "who strongly resembles Ford," according to the affidavit. Ford was pushing a bike.
Five hours later, at about 4:30 a.m., Thompson left his room wearing gray sweatpants that were later recovered, bloodied, from the grocery cart. He soon returned to his room.
Just more than an hour later, Thompson left his room with the bike his acquaintance - presumed to be Ford - had carried earlier. About 15 minutes on, Thompson returned to his room with an empty shopping cart.
Three hours later, about 9:22 a.m., Thompson left his room, looks around the hall and lobby of the building, then retreived the shopping cart from his room, filled with items police later recovered from the shopping cart left in the Othello-area parking lot. He pushed the cart out the back door and headed toward the neighborhood where the Austin Street resident spotted him.
Surveillance footage never captured Ford leaving Thompson's apartment after he entered it the night before.
The affidavit doesn't contain any information on a search of Thompson's room or the nature of the relationship between Thompson and Ford.
Seattle police issued a call for help on Tuesday seeking more information about Ford.
Thompson's criminal history includes attempted first-degree theft, drug charges and assault with a deadly weapon, in addition to several others.
He faces more than 25 years in prison if convicted as charged.
