Authorities said they arrested a convicted robber in Long Beach Friday night after he walked away from a prison camp in San Diego County.

Law enforcement found Marco Calderon, 22, near Cesar E. Chavez Park in downtown, the California Department of Corrections and Rehabilitation said in a news release. He was living out of a car in the area with his fiancé, according to corrections officials.

Calderon had disappeared two days earlier from the McCain Valley Conservation Camp where he was serving a five-year sentence as a minimum-security inmate firefighter, authorities said.

He was last seen in his bunk there around 11 p.m. Wednesday, June 13, according to the news release.

Corrections officers arrested Calderon around 11:50 p.m. Friday, June 15, according to authorities. Investigators were also trying to determine if his fiancé helped him escape, they said.

Calderon was set to be released in November 2020 after completing his prison term for second-degree robbery, but San Diego County prosecutors will now consider filing escape charges against him, corrections officials said.
