(Tucson, AZ) -- A 9-1-1 operator in Arizona is under fire for laughing during an emergency call. A man whose girlfriend was seriously burned when his car caught fire in a remote area north of Tucson was upset when he called for help and heard laughter on the other end of the line. It happened right after the operator asks if his girlfriend is still on fire. The operator says the laughter was unrelated to the call. The Pima County Sheriff's Department is investigating the call.
