PHOENIX (AP) — Authorities still haven't released the identity of a man who fatally shot himself in the head on live national television at the end of a high-speed carjacking chase that began in Phoenix and ended close to the California border.

Fox News was covering the chase that began about midday Friday using a live helicopter shot from Phoenix affiliate KSAZ-TV. The man driving a copper-colored four-door sedan stopped, ran into the desert and placed a handgun to his head and fired.

The man was declared dead at the scene, according to Sgt. Tommy Thompson, a Phoenix police spokesman.
