The suspect's brother, 25-year-old Adrian Virgen, and a co-worker, 32-year-old Erik Razo Quiroz, were also arrested on "accessory after the fact" charges for attempting to protect Arriaga. Authorities say both men are also in the country illegally.
Another brother of Arriaga, 34-year-old Conrado Virgen Mendoza from Chowchilla, and Arriaga's girlfriend, 30-year-old Ana Leyde Cervantes of Newman, were arrested on Friday for aiding Arriaga in evading authorities following the murder of Corporal Singh, Stanislaus County Sheriff's Department said on Friday night. Their booking photos were released, along with that of Arriaga.
Kern County Sheriff's Donny Youngblood said that three additional people were also arrested in the South Valley for aiding and abetting Arriaga.
Stanislaus County Sheriff Adam Christianson says that Arriaga was attempting to make his way to Mexico when he was arrested. He was found at a house in Lamont, California that was being monitored by law enforcement.
According to Kern County Sheriff, when SWAT deputies surrounded that home, Arriaga surrendered without incident. Three additional people were arrested from the house for aiding and abetting, they include 59-year-old Bernabe Madrigal Castaneda, 36-year-old Erasmo Villegas and 57-year-old Maria Luisa Moreno.View image on Twitter
Reggie Singh, brother of fallen Newman Police Corporal Ronil 'Ron' Singh, tearfully thanked deputies after an arrest was made in the case.
Arriaga is accused of killing Corporal Singh when he conducted a traffic stop on Arriaga's pickup truck in the small town of Newman early Wednesday morning, for suspicion of driving under the influence.
As he pulled over the vehicle, Corporal Singh described it to dispatchers as a silver Dodge Ram with paper plates from AR Auto, a dealership in the city of Merced.
Several deputies from both Stanislaus and Merced counties responded, where they found the truck and suspect gone and Corporal Singh lying on the ground. He was rushed to a nearby hospital but died from his injuries.
