The San Francisco Chief Medical Examiner's office confirmed Friday the human body parts found in the suitcase in San Francisco's South of Market neighborhood are those of an unidentified light-skinned male.
The Medical Examiner's office said that the California Department of Justice Bureau of Forensic Servicea DNA Laboratory will be assesting in the identification process.
The case is currently under investigation with the cause and manner of death pending.
Homicide investigators spent Thursday going door-to-door in SoMa looking for surveillance camera video that might show them who left the suitcase on the sidewalk. And they had some luck — one video showing a person pulling the suitcase was recovered from a Goodwill nearby. Police released those images Friday afternoon.
San Francisco police discovered a dismembered body when they opened the suitcase, found abandoned Wednesday on 11th Street near Market Street, a block from Twitter's headquarters. Police then made another gruesome discovery when they uncovered more body parts within a three-block radius.
Police spokeswoman Grace Gatpandan said investigators have a rough description of a suspect but aren't releasing additional details because the investigation is ongoing.
Police also said they have recovered at least one surveillance video from a Goodwill store from Wednesday showing a person with the suitcase.

"It just showed a person across the street pulling like a suit case, that's basically it," Gary Grellman of Goodwill Industries told NBC Bay Area. "Male or female, I couldn't tell. I think it's male."
Officers spent Thursday morning dumping trash cans and looking for body parts or anything that could be linked to the case.
Meanwhile, the discovery has left residents in the area startled and on edge.
"To find something like that, it's just real shocking to me," resident Miguel Valdez said.
