According to KNTV, the Oakland Police Department is investigating, but thus far has not been able to identify the victim or determine a cause of death.
Among the many challenges in doing so is the absence of a head, arms, and legs, notes KRON.
Further, authorities believe the torso had spent about a month in the water and a few days on the rocks.
Johnna Watson, a police spokesperson, said, "The more time a body's in the water the more it's apt to be exposed to all the different elements."
The coroner has determined that the remains are those of a young male and thus far no evidence of trauma has been observed.
