The suspect accused of killing a California police officer the day after Christmas was arrested on Friday, along with his brother, co-worker and three other alleged accomplices, capping a two-day manhunt and providing a platform for the Stanislaus County Sheriff to rip into California's sanctuary laws.

Those identified in connection with the shooting death of 33-year-old Newman Police Cpl. Ronil Singh are: Gustavo Perez Arriaga, who turned 32 on Friday; his brother, Adrian Virgen, 25; and co-worker Erik Razo Quiroz, 32. All are undocumented, Stanislaus County Sheriff Adam Christianson said at a Friday news conference in Modesto, Calif.

Early Wednesday morning, Singh, a narcotics officer with the canine unit, was shot to death outside a market when he pulled over a driver suspected of drunk driving. That man, now identified as Arriaga, took off and was at large until his capture Friday morning. Why Arriaga allegedly shot Singh is unclear, but the sheriff said that Arriaga had two prior DUIs and had been living in the country illegally for several years.

Arriaga is the lone gunman, taken into custody in Singh's handcuffs on a homicide charge in Bakersfield, Calif., where he had been trying to flee to Mexico, the sheriff said. Christianson also said that Arriaga, who worked on dairy farms, was a Sureno gang member and has several aliases and social media accounts. Arriaga was under surveillance for at least 24 hours, Christianson said, adding that hundreds of tips came in leading to his whereabouts in neighbhoring Kern County, about 200 miles away from the shooting.
