California ? A judge denied bail Wednesday for a 25-year-old teacher accused of fleeing to Mexico with a 13-year-old student, and the woman agreed to be transferred from California to Nebraska to face the charges.

Kelsey Peterson’s court-appointed attorney argued for $100,000 bail, but a federal magistrate judge in El Centro ruled she was a flight risk.

The boy immigrated illegally to the U.S. when he was much younger and speaks little Spanish. He shed no tears while Peterson wept as the two parted Friday night at a police station in the border city of Mexicali, according to the Mexican official who captured the pair with the aid of a GPS-enabled cell phone.

“She said to the youngster that she loved him and would always love him in her heart,” said Alfredo Arenas Moreno of the Baja California state police.

Peterson is charged with taking a minor across state lines with the intention of having sex with him. The boy considered Peterson his best friend, but not his girlfriend, and had sex with her “maybe twice,” he said in an interview at a home in Janitzio, Mexico, where he is staying with a family friend temporarily.
