A 37-year-old suspect was fatally shot by San Francisco police early Thursday morning at a home where a 76-year-old woman and a dog were found dead, police said.
Officers were dispatched at about 2:39 a.m. to the residence on the 700 block of 31st Avenue to investigate a report of an aggravated assault in progress, police said.
A responding officer came across an 84-year-old male victim in the doorway of the home, police said. During that interaction, the suspect, who was armed with a knife, "advanced" toward the officer and the elderly man from inside the home.
The officer opened fire, police said. The suspect was taken to a local hospital where he was later pronounced dead.
It's unclear at this time how many shots were fired during the shooting.
The 84-year-old man told officers that the suspect assaulted the 76-year-old woman inside the home, police said.
Officers went inside the home and found the woman and the dog dead. The man was treated for non-life-threatening injuries.

As of Thursday evening, the San Francisco Medical Examiner had not released the names of the suspect or the woman. Police would not confirm a neighbor's report that the suspect was a son of the victims.
"We definitely know that there is a relationship there," Officer Eve Laokwansathitaya said. "I can't say at this time what exactly that relationship is."
