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.

The officer opened fire, police said. The suspect was taken to a local hospital where he was later pronounced dead.
