A 20-year-old Washington state man whose body was pulled from the yacht harbor near the Marina on Tuesday morning was stabbed multiple times in the chest the night before, police said.
Dive teams searched the water Wednesday looking for evidence connected to the case, police Lt. Troy Dangerfield said.
“As far as I know, there was no weapon found, but they are searching,” Dangerfield said.
Police believe that Dennis Knowlton of Olympia, Wash., was stabbed outside a post office in the 3600 block of Buchanan Street near Marina Boulevard between 10 and 10:30 p.m. Monday.
A trail of blood led from there to the water where Knowlton was found.
A green Volvo found down the street from the post office is believed to be connected to the case, but Dangerfield could not confirm it belonged to Knowlton.
According to his Facebook page, Knowlton lived in San Francisco, where he attended City College. He wrote on the page, “Cash Rules Everything Around Me. 20 years old doin it in that California gold sun.”
A friend of his, rapper DJ Memphis 10, memorialized him on a separate Facebook posting showing the pair rapping on video. They were covering a song by the slain rapper Biggie Smalls.
Knowlton was white, about 6-foot-2, and was wearing a white sleeveless T-shirt, blue jeans and red and black tennis shoes, according to police. He may have also been wearing a black shirt at some point in the evening.
