An 18-year-old who has been identified as a suspect in last week's shooting at the Shops at Tanforan in San Bruno remains on the loose, and a fresh manhunt is said to be underway Monday morning.

We learned on Saturday that San Bruno police had identified and arrested two teen boys in San Francisco in connection with the shooting, and that one 18-year-old suspect who was also believed to have been one of the shooters remained at large. That suspect has been identified as Deandre Lejon Gantt of San Francisco, and as KPIX reports today, the search is on for his whereabouts.

The two juvenile suspects, one 16 and one 15, who have not been named, have reportedly not been fully cooperative with the investigation. The 16-year-old was arrested Saturday on suspicion of being one of the shooters, and the 15-year-old, who was part of the same group, was arrested on suspicion of acting in concert with the older boy.

The shooting took place last Tuesday, July 2, on the second level of the San Bruno shopping center, and investigators now say the dispute that led to the shooting was "minor." Surveillance footage shows the groups of boys running and shooting in two directions. The shooting left two boys, one 12 and one 16, with injuries to the leg and abdomen respectively.

The incident also led to the shutting of two BART stations, disruptions across the BART system, and the evacuation of hundreds of people from the mall.

Anyone with information related to the shooting or the suspect at large is urged to contact the San Bruno Police Department at (650) 616-7100 or by email: [email protected].
