SAN FRANCISCO -- Police released surveillance images of what they call a "person of interest' linked to the grisly discovery of human remains stuffed in a suitcase abandoned on a downtown street Wednesday.
Earlier Friday, the medical examiner's office confirmed that the body parts found in the luggage and other remains dropped in a garbage can nearby in the South of Market area came from one, light-skinned man.
Tests have not yet determined how the victim died, but San Francisco police said they're looking to question a man in his 50s or 60s seen in images near the block on 11th Street where the remains were found.
Door-to-door canvassing by police in the SoMa neighborhood paid off with the discovery of footage from a Goodwill store showing a person pulling the suitcase, NBC Bay Area reported.
The person sought by police is a man wearing a baseball cap, a blue-and-orange jacket and light jeans in the footage, and is about 5-foot-7 or 5-foot-8. Police said he may be homeless.
Homicide detectives are investigating, though police have said they need to determine if the unidentified man died from natural causes before someone mutilated his corpse.
