TULSA, Okla. (AP) - Authorities in Tulsa are investigating a shooting that left a 17-year-old boy dead and a 16-year-old girl in critical condition. 

Tulsa Police Sgt. Dave Walker says investigators believe the teens were shot late Tuesday after an altercation with another driver who was stopped at a stop sign. Walker says the other driver apparently opened fire on the teens' SUV after the SUV's driver honked his horn. 

Walker says the 16-year-old was shot at least twice and is in critical condition. The 17-year-old died at Hillcrest Medical Center. Both were passengers in the SUV, and the SUV's driver was not injured. 

Police have not yet released a description of the shooter's vehicle, and no arrests have been made.
