San Jose Police Arrest Suspect Paul Marquez in Alleged Stabbing, Seek Additional Victims
SAN JOSE, Calif. — A man accused of grabbing a stranger and stabbing him multiple times in South San Jose has been arrested on suspicion of attempted murder, according to the San Jose Police Department.
Police identified the suspect as Paul Marquez, who was taken into custody October 3 in San Jose and booked into Santa Clara County Main Jail for attempted murder and assault with a deadly weapon.
The investigation began September 26, 2026, when patrol officers responded to a local hospital to take a report from an adult male being treated for stab wounds.
The victim told officers he had been walking near Branham Lane and Kingspark Drive earlier that day when an unfamiliar man approached him. According to police, the suspect grabbed the victim and stabbed him repeatedly before fleeing.
The victim transported himself to a hospital for medical treatment. The department’s release did not provide further information about his injuries or current condition.
Detectives assigned to the department’s Assaults Unit began investigating the attack. Working with the San Jose Police Department’s Real Time Intelligence Center, investigators obtained footage from City of San Jose public safety surveillance cameras.
Police said the footage helped detectives identify Marquez as the primary suspect. Investigators subsequently obtained an arrest warrant before locating and arresting him.
Authorities released surveillance video connected to the investigation and are asking the public for help identifying any additional victims.
Because of the nature of the attack, detectives believe other people may have experienced similar incidents. The release did not identify a suspected motive or describe other attacks.
Anyone with information about this incident or similar cases is asked to contact Detective Wilson, badge number 4917, with the San Jose Police Department’s Assaults Unit at 4917@sanjoseca.gov or 408-277-4161.
The allegations remain subject to court proceedings.
