Police officers found the victim lying on the pavement, provided first-aid, and called medics for life-threatening injuries to transfer him to a hospital. However, the old man died on Saturday while he was still in the hospital.

A male attacker ran from across the street to push the victim, causing him to fall to the ground, police said. After that, the suspect fled with a female friend.

Authorities arrested Watson and charged him with elder abuse causing great bodily injury, assault with a deadly weapon, and one count of murder. Officials also took a woman into custody and charged her with one count of accessory after the fact. The woman, 20-year-old Maylasia Goo, was from Daly City, similar to Watson.

Officers from the San Francisco Police Department’s Tactical Unit and Homicide Detail served a search warrant on the 500 block of Lisbon Street in Daly City, ABC7 News reported.
