CROWN POINT, Ind. (AP): A sheriff says authorities tracked an escaped northwestern Indiana inmate and his girlfriend using GPS coordinates through a cellphone the couple purchased.

Lake County Sheriff John Buncich said Wednesday that authorities tracked 22-year-old Richard Campos of East Chicago and 20-year-old Elysia Jeronimo of Hammond to Texas through the phone purchased after the escape.

Police say Campos and Jeronimo were taken into custody in San Antonio late Tuesday.
Buncich says prosecutors have begun extradition proceedings against the two.

Campos and Jeronimo were charged Monday with felony escape. Court documents show Campos and Jeronimo came up with a plan to help him escape from the Lake County Jail on Saturday when he was on laundry duty.

Buncich says three jail guards will face administrative charges over the escape.
