The shooting and manhunt in California's agricultural Central Valley entered the national debate over immigration, after Trump tweeted about it in his advocacy for a border wall and Christianson criticized California's sanctuary law for immigrants.
That's about 320 km southeast of where Cpl Ronil Singh was shot before dawn on Wednesday after stopping a suspected drunken driver. He discharged his gun while trying to defend himself.
Christianson described Arriaga on Friday as an undocumented immigrant from Mexico, who crossed over the border into Arizona several years ago. Both men also were in the country illegally, he said. He doesn't belong here. Christianson didn't say when the 33-year-old came to the USA but that the Mexico native has been living here for several years. "He is a criminal", the sheriff told reporters.
The suspect had fled the scene in his vehicle prior to assisting officer's arrival.
If you see him, you're urged to stay away the suspect, and call 911 immediately. Sheriff's officials, however, say they can not confirm the suspect's name and date of birth.

A piece of police tape is strung across North Camden Street on June 24 in Minneapolis, Minnesota.
Singh was the first officer with the Newman Police Department to die in the line of duty, Chief Randy Richardson said. The Stanislaus County Sheriff's Department shared that their son was 5 months old.
The Stanislaus County Sheriff's Department said it would address "significant developments" in the investigation during a news briefing early Friday afternoon.
Outgoing California Gov. Jerry Brown offered condolences to Ronil Singh's family and said flags at the Capitol would fly at half-staff in his honor.
The Stanislaus County Sheriff's Office previously said that it will announce "significant developments" in the search for the man suspected of a killing an officer in Newman.
President Donald Trump, who is using the ongoing shutdown of the federal government as leverage to obtain funding for his proposed border wall, cited Singh's death on Thursday to bolster his argument.
Right-wing commentators used the killing to rail against illegal immigration. The 33-year-old had gang affiliations and multiple Facebook pages with different names, Christianson said. The dirt bag who took his life is an ILLEGAL immigrant who has no right to be here.More news: Putin praises new hypersonic Avangard weapon after test
