RANCHO CUCAMONGA – A few hours after a 45-year-old security guard was shot to death, San Bernardino County Sheriff’s deputies tracked down the suspect and arrested the man they believe pulled the trigger. Diego Dominguez, 36, of Rancho Cucamonga was arrested after deputies stopped the vehicle he was driving when he was leaving his home early Sunday morning.
Hours before, in an attempt to rob The Brother’s Liquor Store at Arrow Highway and Hermosa Ave., investigators said that Dominguez shot Dean Vedol Sena, a security guard hired to watch the stores. Reports stated that Dominguez entered the store at about 11:20 p.m. at which two clerks were on duty.
“(Dominguez) brandished a dark-colored handgun,” said Corporal Randy Naquin, a San Bernardino County Sheriff’s deputy. “One of the clerks was able to leave the minimart. The other clerk was behind the counter.”
While Dominguez demanded cash from the register, said Naquin, the remaining clerk complied with his requests. Meanwhile the other clerk had notified Sena, the security guard who worked in the area. Sena, who was armed, entered the store and was shot multiple times by Dominguez, said homicide investigators, who then fled on foot. Naquin said Sena was not able to get his weapon out of his holster to return fire. Sena died at San Antonio Community Hospital in Upland.
Deputies were able to view store videotape and identify a possible suspect, eventually tracking Dominguez to a local address. He had entered the store wearing a hoodie, a bandana covering his face and had eyeglasses on.
Once deputies stopped Dominguez’s vehicle near his residence at the 9900 block of Placer St. at 8:30 a.m. on Sunday, deputies served search warrants for his car and residence. Dominguez is being held at West Valley Detention Center in Rancho Cucamonga.
