A storm chaser featured on the Weather Channel has been killed in a head-on collision in northeastern Oklahoma. The Oklahoma Highway Patrol hasn’t released the names of those killed in a double-fatality accident on the Turner Turnpike in Sapulpa Saturday afternoon, but the Weather Channel said one of them was storm chaser Andy Gabrielson, who worked on their show "Tornado Hunt." CBS Affiliate KOTV reports Gabrielson’s car was hit head-on by another going the wrong way.
