CINCINNATI (AP) — Authorities are trying to confirm the identity of a teenager who told police he is an Illinois boy missing since 2011.

A 14-year-old boy told police in Newport, Kentucky, on Wednesday that he escaped two kidnappers in the Cincinnati area and ran across a bridge. He said his name was Timmothy Pitzen.

In 2011, then-6-year-old Timmothy Pitzen’s mother picked him up at school in Illinois, took him to the zoo and a water park, and later killed herself at a hotel, leaving a note saying her son was fine but that no one would ever find him.

Police from Aurora, Illinois, sent two detectives to the Cincinnati area, where the FBI and local police are investigating. The boy was taken to a hospital, but no information was released.
