A man who shot himself to death Friday on the side of Interstate 19 following a minor collision has been identified as a 53-year-old Tucsonan.
Norman Daniel Yingling had been suffering from depression, his family told police.
The fatal shooting occurred in public sight on I-19 south of Tucson.
Yingling was backed up in traffic following an unrelated fatal crash when he rear-ended a vehicle.
He then walked 20 to 30 yards to the side of the highway and shot himself, Tohono O'odham police said.
Officers found two 9 mm handguns at the scene, including a Ruger next to Yingling's body, Tohono O'odham Detective Marty Fuentes said. He also had a derringer in his pocket, Fuentes said.
The person who was rear-ended in that collision was taken to a hospital as a precaution.

Her vehicle was struck from behind, and Zarate De La Rosa - a Phoenix resident - had to be taken to a hospital, where she was pronounced dead.
The driver of the vehicle that rear-ended her suffered non-life-threatening injuries.
