UPDATE:  The body of Bradley Powell, 23, was found inside a shallow grave on February 3rd. He was first reported missing in December of last year.

Powell's father said he's now looking for answers.

"From December 7th til now, it's just been a big nightmare," Cory Powell said. 

Powell's father said he's now living with an empty space in his heart. His son was taken from him, and he still doesn't know why.

"His whole life has been flashing in front of my face, from when he was born, I held him first, I named him," Cory Powell said. 

Police believe Cory Powell's only son was murdered but have shared very few details with the public.

"I'm glad we brought him home, but now it's just finding out who's responsible for his death," he said. 

Powell said his son was an all-star athlete growing up, he was always surrounded by family and friends. Now the family wants answers.

"It's just horrific, I can't imagine why," Powell said, "Especially Bradley, the type of person he was, his upbringing, he wouldn't hurt anyone."

Powell knows police have been receiving tips that led to the discovery of his son's body. Now he hopes more tips will lead to his killer.

"They could just go to the police, be anonymous, you know this is a really big deal," he said. 

Powell's body was taken to the GBI crime lab for an autopsy. His cause of death has not yet been released.

A memorial service was held for Bradley Powell last Friday at the Hamilton Funeral Home.
