Paul Schwarz of the Lexington Police Department in Nebraska said the white Pontiac owned by 25-year-old Kelsey Peterson crossed into Mexico around 11 p.m. on Tuesday.

Peterson, a math teacher and basketball coach at Lexington Middle School, fled with the boy after police began investigating whether the pair had an intimate relationship, authorities said.

Authorities believed the two were traveling together in Peterson's car, and police nationwide were notified about them. Court documents said the boy was last seen Oct. 26.

A judge issued an arrest warrant Monday charging Peterson with kidnapping, child abuse and contributing to the delinquency of a minor.
