Names of parties involved in a Kingman homicide and some details of the Feb. 11 incident on Interstate 40 are beginning to surface. The Department of Public Safety said Bradley Stumpf, 31, has admitted shooting the victim Jason McCafferty, 46, believed to be a Kingman area resident.
Stump’s reported confession is laid out in a probable cause affidavit that the Department of Public Safety filed in Kingman Justice Court. The report indicated that the men had been performing survey work in the Phoenix area and were returning to Kingman when the shooting was reported on the Stockton Hill Road off ramp at 10:49 p.m.
Stumpf told investigators that McCafferty had been yelling at him during the drive.
“Stumpf stated that he has been hearing voices in his head for the last several months and he was experiencing that while in the vehicle,” the affidavit stated. It said Stumpf had been holding a 9 mm. handgun in his lap and that he remembered pointing it at McCafferty before briefly blacking out.
“Stumpf stated that he remembers the gun going off and the vehicle going out of control,” the affidavit said. “Stumpf said he had to push down on the brake to get the vehicle to stop.”
Stumpf told DPS that he tucked the weapon between the seats and fled on foot to a Kingman area residence where he sometimes stays. An unidentified party at that residence told DPS that Stumpf entered the home and “looked at her with a blank stare” before indicating that McCafferty had apparently killed himself by the freeway.
Another party whose name is redacted from Court records told DPS that between the shooting and his arrest that “Stump was acting very erratic and at one point was laying on the floor in the fetal position saying ‘just kill me, just kill me,’” the affidavit stated.
The woman told investigators that Stumpf claimed he had an infection in his head and wanted to be checked into a mental hospital. Stumpf was booked into jail on a second degree murder charge and he awaits a preliminary hearing scheduled Feb. 22.
