By Richmond Police Department
An attempted homicide suspect has been arrested two days after an incident that occurred on the evening of July 12, 2026, in the 100 block of Harbour Way South.
At approximately 9:41 p.m., Richmond Police officers responded to a report of a traffic collision and a victim suffering from a gunshot wound in the 100 block of Harbour Way South. Officers arrived on scene and found one of the drivers of the traffic collision suffering from gunshot wounds. The victim was transported to the hospital and is in stable condition.
During the preliminary investigation, officers determined two vehicles were involved in the minor traffic collision. For unknown reasons, an occupant of one of the vehicles involved in the collision shot at the other involved vehicle, striking the driver of the vehicle. The shooter then fled on foot from the scene of the collision. Officers quickly identified 18-year-old Anderson Marroquin as the suspect in this shooting. Officers also determined that Marroquin had an active PC 187-Murder warrant for his arrest out of the city of Vallejo. The Richmond Police Department Homicide Unit responded and assumed responsibility for the investigation.
On July 14, 2026 (two days after the shooting), Detectives learned Marroquin was in the city of Palo Alto. With the assistance of the Palo Alto Police Department, Marroquin was arrested for PC 664/187 -Attempted Homicide and the Vallejo Police Department’s murder case. The Vallejo Police Department took Marroquin into custody and subsequently booked him into the Solano County Jail on an outstanding warrant. The Attempted Homicide case that occurred in the City of Richmond is being forwarded to the Contra Costa County District Attorney’s Office for them to review and file charges.
According to localcrimenews.com, the five-feet, five-inch tall, 220-pound Marroquin is Hispanic.
This arrest highlights the outstanding work and collaboration between the Richmond Police Department, Palo Alto Police Department, and Vallejo Police Department in quickly bringing a violent offender into custody.
