An Arizona man is facing a second-degree murder charge after allegedly shooting and killing another driver during a heated road rage confrontation, then calling 911 to claim he was simply defending himself.
But investigators say evidence recovered at the scene raises serious questions about his account of the deadly encounter.
William McGinty, 43, was arrested Tuesday, November 3, after a dispute between two motorists on Loop 101 in Scottsdale escalated into gunfire near 87th Street and Cactus Road.
According to court documents, the confrontation began around 2 p.m. when McGinty attempted to exit the highway at Cactus Road. He told investigators the other driver refused to let him merge, sparking an argument that continued after both vehicles left the freeway.
McGinty claimed the other motorist suddenly cut in front of his car and stopped, forcing him to slam on his brakes.
The man then allegedly got out of his vehicle, approached McGinty’s driver’s-side window and repeatedly demanded that he get out.
But instead of driving away, McGinty pulled out a handgun.
“I don’t want no beef,” McGinty claimed he told the approaching driver while holding the weapon against his chest.
According to his account, the man continued approaching and appeared ready to punch his car window. McGinty told detectives he fired one shot because he feared for his safety.
What happened next became a particularly troubling part of the investigation.
McGinty allegedly told police his gun malfunctioned after the first shot, forcing him to adjust a screw on an attached suppressor before firing a second time as the other man turned toward him again.
The victim, whose identity had not been publicly released, was struck in the chest and back.
After the shooting, McGinty called 911 and reported that another driver had been behaving aggressively toward him.
When the dispatcher asked how he had defended himself, McGinty allegedly responded, “My pistol.”
He also acknowledged that the other man did not appear to have a weapon.
McGinty remained inside his vehicle while waiting for officers, telling the dispatcher he would stay put until police arrived.
Responding officers found him with his hands raised outside his car window and took him into custody without incident.
Nearby, they discovered the wounded motorist lying on the roadway. Emergency personnel rushed him to a hospital, but he died from his injuries.
As detectives examined the scene, they uncovered details that appeared to conflict with McGinty’s description of the confrontation.
Although he claimed the other driver had threatened to strike his window, investigators found no broken glass or visible damage to either vehicle.
Police also reviewed traffic camera footage from the area, hoping to determine what led to the fatal encounter.
According to court documents, the footage showed no aggressive driving behavior by either motorist, raising additional questions about McGinty’s account of the events preceding the shooting.
Investigators have not publicly established whether the deceased driver physically attacked McGinty or made any attempt to enter his vehicle.
The case now centers on whether McGinty reasonably believed he faced an immediate threat that justified using deadly force.
Under Arizona law, a person may use deadly force in self-defense only under circumstances involving a reasonable belief that such force is immediately necessary to protect against another person’s unlawful deadly force.
Simply being involved in a heated traffic argument does not, by itself, justify shooting another driver.
McGinty was booked into the Maricopa County Jail on suspicion of second-degree murder, with his bond set at $1 million.
The Maricopa County Attorney’s Office is responsible for reviewing the case and determining how the prosecution will proceed.
Scottsdale police described the shooting as an isolated incident and said there was no ongoing threat to the community.
For the victim’s family, however, an ordinary afternoon drive ended in an unimaginable tragedy.
What began as an apparent disagreement over merging onto a highway exit left one man dead and another facing the possibility of years behind bars.
McGinty maintains that he acted in self-defense, but investigators are continuing to examine the physical evidence, witness accounts and traffic footage to determine whether his use of deadly force was justified.
