San Francisco Police Arrest Muni Stabbing Suspect 21-130(a)

On Thursday, June 10, 2021, at approximately 4:30 p.m., San Francisco Police officers from Northern Station responded to the area of Steiner and Green Streets regarding a stabbing that took place on a Muni bus. Officers located the 31-year-old male victim on the bus suffering from stab wounds. Officers rendered aid to the victim and summoned medics to the scene. The victim told officers that he was seated on the bus when the suspect, who was sitting adjacent to him, stood up and stabbed him two times. The suspect then exited the bus and fled on foot. The victim did not know the suspect, had no prior interaction, and said the attack was unprovoked.  The victim was transported to a local hospital where he was treated for non-life-threatening injuries.

The San Francisco Police Department’s Muni Task Force (MTF) assumed the investigation and circulated a crime bulletin to law enforcement.  On July 3, 2021, at approximately 3:49 p.m., an off duty SFPD officer saw the suspect near Steiner and McAllister Streets having recognized him from the crime bulletin.  The officer contacted colleagues from SFPD’s Northern Police Station who responded to the scene and detained the suspect.  Through the course of an investigation, the officers developed probable cause to arrest 32-year-old San Francisco resident Mario Xavier Hills for the June 10th stabbing. Hills was later booked at the San Francisco County Jail for assault with a deadly weapon (254(a)(1) PC), battery resulting in serious bodily injury (243(d) PC), battery of a mass transit passenger (243.3 PC). Evidence, including a knife was also recovered.

While an arrest has been made, this remains an ongoing investigation. Anyone with information regarding this incident is asked to contact the SFPD via the SFPD 24-hour-tip line at 1-415-575-4444, or Text a Tip to TIP411 and begin the message with SFPD. You may remain anonymous.
