A man suspected of fatally shooting one man and injuring another Monday on the northwest side checked into a hospital with injuries, authorities said.

Pima County Sheriff's deputies responded to the shooting in the 3500 block of West Amber Terrace at about 4 p.m., said Deputy Ryan Inglett, a department spokesman.

The area is near West Orange Grove Road and North Camino de la Tierra.

Deputies found Jaisaac Sloan, 21, and Austin Buckshaw, 20, with gunshot wounds, Inglett said. Deputies gave aid to the men, but Sloan was pronounced dead at the scene. Buckshaw, who was seriously injured, was taken to Banner-University Medical Center Tucson.

Inglett said deputies learned that Sloan and Buckshaw, who both knew each other, were in a camper trailer with other people when the shooting occurred. He said the man suspected in the shooting pulled a gun from a backpack and began to fire.

During the incident, the man who is suspected of firing the shots, was injured and he checked himself into the hospital, Inglett said.

Homicide detectives have taken over the investigation.

No further information was released Monday night.

Detectives ask that anyone with information call 911 or 88-CRIME, the anonymous tipster hotline.
