Danville police are investigating a rowdy house party and fight early Sunday -- with one of the party attendees, a 20-year-old Concord man, discovered dead a day later.
Police and Contra Costa County Coroner's officials said Wednesday that the body of Devin Knoll, found by Concord police at his apartment in the 5000 block of Valley Crest Drive at 4:22 p.m. Monday afternoon, showed no obvious signs of trauma from a fight, and the altercation has been ruled out as a cause of death. Toxicology tests are pending, but Concord police said preliminary findings concluded his death was "medical in nature and not the result of a criminal act."
Concord and Danville police had been investigating since the body's discovery Monday. No arrests have been made.
Danville police Chief Steve Simpkins said his officers were called to the raucous party early Sunday morning and learned of the fight, in which Knoll was involved.
"We're certainly not going to stop investigating the fight," he said. "There's a lot of people to interview, and it's going to take some time."
Attempts to reach Knoll's family were not successful by press time.
