LAS VEGAS -- The family of Chris Privett wept in court Monday. So did the family of his killer, Gerald Davison.

But the 17-year-old simply smirked in court and offered a halfhearted apology for shooting the Palo Verde High School student in February 2008.

"I dont know how to apologize for for taking your son's life away," he said, shrugging his shoulders. "Sorry ain't going to cut it but that's all i can tell y'all. Sorry."

Davison, who took a plea deal, was sentenced to 28 years to life for killing Privett.

The driver of the car, Ezekial Williams, also pleaded guilty, admitting, “I handed Gerald the gun.” He was sentenced to eight to 20 years in prison.

Witnesses said Privett, 15, and his friends flashed gang signs at Williams and Davison before the shooting, as they walked home from Palo Verde High School.

Williams’ attorney told FOX5 the shooting was a “dumb decision.” The explanation didn’t satisfy Privett’s parents, who lambasted Williams at his sentencing in August.

“I put ashes of my son in creeks, mountains and the ocean, so, when I see those things, I’ll remember him," his father Michael Privett said. “I just don’t understand why somebody 18 years old would think it was OK to take a gun, encourage your friend to shoot at three kids who weren't doing anything to you.”
