A 19-year-old Hayward man and three East Bay boys were arrested early Wednesday on suspicion of burglary at Target Masters on Minnis Circle near Milpitas Police Department, police announced.

At 1:48 a.m., an on duty Milpitas police sergeant preparing to leave the station heard an audible alarm sounding from the gun store and shooting range at 122 Minnis Circle. The sergeant saw a 17-year-old Hayward boy stumble off of the rooftop and run to a silver 1999 Toyota Camry, which was occupied by a 15-year-old Oakland boy, police said. The 17-year-old entered the driver’s seat of the vehicle and drove away northbound on Minnis Circle. The suspect vehicle and occupants were stopped by a second responding officer on the 1333 block of Minnis Circle.

Both juveniles were taken into custody without incident.

At Target Masters, the sergeant encountered a third suspect attempting to exit the front glass doors of the business and noticed the suspect was allegedly carrying a firearm. The sergeant ordered the suspect to drop the firearm and to remain still which he complied.

During the investigation, officers learned a fourth suspect was not accounted for and his whereabouts were unknown. The Santa Clara County Sheriff’s Office and San Jose Police Department assisted to establish a large perimeter and begin a search, police said. As a Milpitas police officer and sheriff’s deputies searched the city’s Department of Public Works Corporation Yard, located directly south of Target Masters, they located Jose David Fernandez, 19, who fled over a 10-foot wall and ran south along the railroad tracks.

The suspect was taken into custody without incident.

In conjunction with the San Jose Police Department canine unit, Milpitas SWAT officers unlocked the front doors of Target Masters and took a second 17-year-old Hayward boy into custody, who was allegedly in possession of two stolen handguns from the business. No additional suspects were located and the case remains under investigation, police said.
