UPDATE 2:30: The Wyoming Highway Patrol says that the Casper shooting suspect, Arturo N. Ledezma of Salt Lake City, died of a possible self-inflicted gunshot wound. This followed a 16-mile chase east of the city of Lyman last night. Ledezma approached a roadblock on I-80 but refused to stop, leading to the pursuit. He ultimately slammed his car into a bridge abutment. Patrolmen report they walked up to the car after the crash and found Ledezma had apparently shot himself.

Arturo N. Ledezma of Salt Lake City died in a single car crash shortly before 9 p.m., a Wyoming Division of Criminal Investigation officer said Thursday. "Last night, during the later evening hours, highway patrol had identified the suspect vehicle from the Casper shooting earlier in the day on westbound Interstate 80 on the outskirts of Green River," said Kebin Haller, DCI Deputy Director of Operations. Two highway patrol vehicles followed Ledezma's car, "Haller said. "They followed the vehicle for some time, and when a traffic stop was initiated, the suspect fled westbound," he said. "Troopers continued to follow the suspect, and around mile marker 40, it appeared the suspect drove right into the bridge barrier, the frames around the bridge, on the interstate," Haller said. Mile marker 40 is near Lyman. "When troopers approached, the suspect appeared to be deceased, and at that point, because of the pursuit their policy indicated they should contacted DCI and we did respond," he said. Haller did not know how fast Ledezma was driving during the chase. The female shooting victim is in stable condition at the Wyoming Medical Center. DCI and Casper Police are continuing the investigation.
