An 18-year-old man was arrested as the suspect in a violent assault on a pedestrian last week in Palo Alto, police said.
Shortly after 7 p.m. Friday, officers responded to a medical call near the intersection of Lytton Avenue and Seneca Street, where they found a man in his 80s on the ground conscious but suffering from several injuries to his face and neck, including stab wounds.
The victim was transported to a hospital, where he remains hospitalized.
According to officers, a witness saw a teenager running from the scene.
Two women later identified as the suspect's family members arrived at the scene and asked officers if they had seen their relative, who they said had called and asked for a ride.
An investigation, including reviewing video footage from nearby homes, led to the identification of the suspect as Andrew McMenomy-Cortez of Palo Alto.
Police said it appeared the victim struck up a conversation with the suspect, and the two walked together for some time before the assault.
