A jogger along Marina Green spotted the body of a 19-year-old white male floating in the water at about 6:30 a.m. Tuesday, sending out police officers. The Marina Green neighborhood was quickly engulfed in a sea of yellow police tape as the investigation began to take some twists.
The Marina is at the foot of Buchanan.
"There is a post office right there at Buchanan and Beach, right there on the corner," said SFPD Lt. Troy Dangerfield. "The blood trail seems to start in that doorway and go all the way across the street, crossing Marina Boulevard, all the way towards the tree line towards the pier."
The victim had apparently been stabbed.
"It appears that it was an etched weapon that resulted in most of the wounds," said SFPD Chief Greg Suhr. "I don't know the exact cause of death. That will be determined by the medical examiner."
A resident of the area saw the trail of blood Monday night and called police.
"Police did respond out last night," said Dangerfield. "They searched the area of the parking lots, they looked in the vehicles, but they did not find any victims at that point."
There are questions as to why they didn't resume a search earlier Tuesday morning.
The investigation expanded as officers zeroed in on a green Volvo that was parked two blocks away from the water. It has Washington state plates and a sticker from a military base, Fort Lewis. ABC7 checked with Fort Lewis and they are not reporting anyone missing.
But Marina residents say two apparently homeless men have been living in that car, sleeping there at night, and then leaving during the day. That car has been impounded. There is no connection at this point between the body found and that car.
Anyone with information about the case is asked to call the Police Department's anonymous tip line at (415) 575-4444 or send a tip by text message to TIP411.
