SFPD Arrests Stabbing Suspect #26-095

Quick Response by Patrol Officers and Drones Locates Suspect

On July 25, 2026, at approximately 4:09 p.m. San Francisco Police officers responded to the 1100 block of Mission Street for a report of a stabbing. The suspect fled the scene on foot and was last seen running on Mission Street.

SFPD officers assigned to the Real Time Investigation Center (RTIC) immediately reviewed surveillance cameras and located the suspect, who was wearing a multicolored windbreaker, running eastbound on Mission Street and eventually onto Minna Street.

While monitoring surveillance footage, RTIC investigators observed the suspect crouch between two parked vehicles on Minna Street, where he changed his clothing and threw a black bag onto the roof of a nearby building before continuing on foot.

RTIC investigators immediately disseminated updated images of the suspect to sworn personnel and provided responding officers with the suspect's direction of travel. Southern Station patrol officers quickly located the suspect on the 400 block of Minna Street. After a brief foot pursuit, officers took the suspect into custody without further incident.

With the assistance of SFPD's Drone as First Responder (DFR) program, officers located the black bag that was thrown by the suspect onto the rooftop. A search of the bag resulted in the recovery of a bloody knife believed to have been used in the assault.

RTIC investigators reviewed the surveillance footage further and observed the suspect place something underneath a parked car after he changed clothes. An officer responded to the scene and located the distinct jacket and hat that the suspect was wearing during the stabbing.

The suspect is identified as 36-year-old male Lamedh Porter of Pleasant Hill and was transported to the San Francisco County Jail, where he was booked on charges including aggravated assault (254(a)(1) PC) and resisting arrest (148(a)(1) PC).

Although an arrest has been made, this remains an open and active investigation. Anyone with information is asked to contact the SFPD at 1-415-575-4444 or Text-A-Tip to TIP411, beginning your message with "SFPD".
