The 65-year-old man who was beaten by a woman wielding a metal cane last week has died — and police say the fatal blows came during an argument over a slice of pizza.

The San Francisco Medical Examiner’s office identified the victim as Harvey Grosser, of San Francisco. His death is now being investigated as a homicide, said Mark Powning, an investigator for the medical examiner.

The incident occurred in the South of Market neighborhood on Sixth Street just before 1 a.m. on Sept. 6. Officers reviewed surveillance footage showing the unidentified woman hitting Grosser with the cane.

Police were still searching for the assailant Wednesday. The investigation is ongoing.

San Francisco Police Chief Bill Scott announced the death on Wednesday evening during the Police Commission meeting. Grosser’s family has been notified.
