He went out with some friends, but never came back home.
Now, nearly four years later, the family of a missing southern Kentucky man says they just want closure.
Christopher Gregory was 21 years old when he disappeared in January, 2006.
His mother, Rhonda Gregory, says she's felt only grief since then.
She says the last time she spoke to him, he told her he was going to hang out with some friends.
But when he didn't return home when he said he would, she started calling him. He never picked up.
She says the friends he was with claimed they didn't know what happened to him. Several days later, police found Christopher's car at a bowling alley. They also found his ID and other documents on the side of a road.
Rhonda Gregory is again asking anyone who might have even the smallest clue about what happened to her son to come forward and contact the police.
Anyone with information about Christopher Gregory's disappearance is asked to call the Russell Springs Police Department at 270-866-3636.
