Suspect in stabbing at a Garden Grove McDonald’s , Oct. 29, 2018.

GARDEN GROVE (CBSLA) — Police are searching for a suspect who stabbed an elderly man several times in the restroom of a McDonald’s in Garden Grove Saturday.

The stabbing occurred at a McDonald’s in the 13900 block of Harbor Boulevard at about 10:52 a.m., according to Garden Grove police.

The victim was discovered in the men’s restroom with multiple stab wounds to his upper body and was rushed to a local hospital, police said. His injuries were not believed to be life-threatening. He was reported in stable but critical condition Monday night.

Surveillance video showed the suspect exiting the restroom soon after the victim had entered, police said. It then showed him leaving the McDonald’s and running through the parking lot.

Virginia Mangione, the owner-operator of the McDonald’s location, said in a statement released to CBSLA: “Our thoughts are with the victim’s family and loved ones. We are working with law enforcement as part of this ongoing investigation. Our top priority is always the safety and well-being of our employees and customers at our restaurants.”

The motive in the stabbing remains unknown, and it does not appear to have been a robbery attempt. Following the attack the restaurant was closed for several hours while police investigated.

The suspect is described as Hispanic, between 20 and 30 years old, 6 feet tall with a medium build.

Anyone with information on the suspect’s identity should call detectives at 714-741-5800.
