SUBJECT:  Suspect Arrested After Stabbing Victim in Grocery Store
 
LOCATION: 1071 El Camino Real, Redwood City
 
DATE/TIME: May 9, 2026, Approximately 10:59 P.M.
 
On May 9, 2026, the Redwood City Police Department received numerous 911 calls reporting an altercation involving a stabbing and possible shooting at the Safeway located at 1071 El Camino Real in Redwood City. Officers responded immediately and, upon arrival, several witnesses pointed out the suspect. Officers detained the suspect without incident.
 
Responding officers located an adult male victim suffering from a stab wound to the abdomen, along with several additional superficial wounds consistent with an edged weapon assault. Redwood City Fire Department personnel responded to the scene and provided medical treatment.
The preliminary investigation revealed the following:
 
Two victims were in the self-checkout area of the store when the suspect approached the adult male victim and, without apparent provocation, began assaulting him with a knife. During the attack, an adult female victim used a shopping cart in an attempt to fend off the suspect and protect the male victim.
 
At some point during the altercation, the male victim produced a firearm and discharged a single round. The suspect then fled from inside the store into the parking lot area, where he was quickly detained by responding officers.
 
The discharged round struck a computer monitor inside the store and no injuries resulted from the gunfire.
 
At this time, it is unknown whether the victims and suspect knew each other prior to the incident. Investigators do not believe any additional suspects are involved, and there is no ongoing threat to the public.
 
The suspect was identified as 31-year-old Isidro Zamora-Cisneros of Redwood City. He was arrested and booked into the San Mateo County Maguire Correctional Facility on the following charges:
 

• 664/187 PC – Attempted Murder
• 11377(a) H&S – Possession of Methamphetamine
