Andre Jamil Townsend's 9-year-old son came home just after 3:30 p.m. and found Townsend near the front door suffering from gunshot wounds, South San Francisco police Sgt. Joni Lee said.
Officers responded to the home in the 3700 block of Radburn Drive and pronounced Townsend dead at the scene, according to Lee.
No suspects have been arrested in connection with this homicide, Lee said.
The shooting is being investigated as a homicide because no weapon was found at the scene, and the location of Townsend's gunshot wounds were not consistent with a suicide, Lee said.
An autopsy is scheduled to be conducted on Townsend this morning, according to Lee.
