ATOKA COUNTY, Okla. (KXII) -- Court documents show that the 20-year-old arrested for murder in Atoka County killed his own father after an argument over an unplugged electrical cord.
Though the son claimed the shooting was an accident in his 911 call, authorities said they think he's lying.
"My dad has been shot in the chest and he's dying on me," Wyatt Arp said in his call to 911.
That's what 20-year-old Wyatt Arp said when he called 911 Thursday night after investigators said he shot his 55-year-old father Douglas Arp with a rifle as he was laying on a couch.
"Did somebody shoot him or was it an accident?" the dispatcher asked.
"It was an accident, the gun fell off the rack and it was loaded and it hit the fire trim and it killed him," Wyatt answered.
That was Wyatt's story the night of the shooting.
"So the gun was on the ground when this happened?" the dispatcher asked.
"Yes," Wyatt answered.
But investigators said the evidence tells a different story.
"I have moved the gun since, but I don't want you to charge me with murder, because I didn't do it," Wyatt said to the dispatcher.
Based off of the gunshot wound, the medical examiner believed the gun that fired the bullet was almost directly in front of Douglas, not on the ground.
So Monday morning, an OSBI agent interviewed Wyatt again. The court documents show that this time, his story was this:
He and his father got into a fight Thursday after Douglas unplugged the electrical cord to Wyatt's mobile home, right behind his. Wyatt went home to cool off and when he came back to his father's home, Douglas wouldn't let him in so he crawled through a window.
Wyatt then picked up a rifle, saw that it was loaded and tried to put it in a safe position, but he claims his thumb slipped, firing a shot into his father's chest.
"He is dead, my dad is dead," Wyatt said in the 911 call.
The agent said evidence led him to believe the shooting was not accidental and arrested Wyatt for first degree murder.
He is still in the Atoka County Jail.
