OREGON CITY, Ore. -- Police found a 13-year-old girl after she was reportedly abducted Tuesday night in Washington state, triggering an Amber Alert.

The girl was found unharmed at a migrant labor camp south of Portland after police tracked a cell phone call by the 23-year-old man who allegedly abducted her.

The man who allegedly abducted her, Gabriel Flores-Lopes, 23, was in police custody, deputies said. Flores-Lopes once lived with the girl's family, said Mark Clemens, a spokesman for the Washington State Emergency Management Division in Olympia.

Flores-Lopes had called associates in Molalla, and police used information from that call to track him to a Clackamas County address, said Deputy Angela Brandenburg, sheriff's spokeswoman.

Amber Alerts are bulletins, distributed through radio and television broadcasts and electronic highway signs, on kidnapped children and their abductors. They are named after Amber Hagerman, a 9-year-old girl abducted and later found murdered in Texas.
