On Nov. 29, a 73-year-old North Carolina man and his 23-year-old grandson drove to Columbus County to buy a 2011 Chevy Camaro they’d spotted on Craigslist.
Now the grandson, Tristan Lavonne Stavee, is dead and his grandfather, George Cleveland Stump Sr., 73, is fighting for his life after they were allegedly robbed and then shot, say police.
"They killed my son and he's only 23,” Leeann Stump, Stump Sr.’s daughter and Stavee’s mother told WRAL.
“And my dad ... they don't know if he's going to make it or not," Stump said. "They were just ambushed, and they stole the money and beat and shot both of them."
On Nov. 29, just after 9 p.m., the Columbus County Sheriff's Office was called to the 100 block of Sellers Town Road in Whiteville after a man was found unresponsive on the ground, the sheriff’s office says in a statement.
Upon arrival, deputies located the grandfather inside a vehicle, suffering from a gunshot wound but still responsive, the sheriff’s office says.
His grandson, the father of two little girls, who was on the ground outside of the vehicle, was also shot.
Whiteville Rescue arrived on the scene and transported Stump to a nearby hospital in critical condition.
Stavee died at the scene.
On Thursday, the sheriff's office announced that it had made two arrests in the case.
On Dec. 2, authorities arrested Mark Anthony Nelson, 24, of Tabor City at his home.
