Adre'Anna's body was later found two weeks ago in a field in Lakewood by two young boys, who did report their finding to police.

Police had been looking for Grant, not as a suspect, but as someone who may provide clues they need.

In a jailhouse interview, Grant told KOMO 4's George Howell that he found the bones weeks before, and told more than 20 people about his discovery. But he didn't go to police because he has a criminal past, had outstanding warrants and didn't want to go to the police as the guy who found the bones.

"I feel bad for not saying anything sooner," Grant said. "But I figured she was already gone."

Grant admits he was hiding out at a friend's house, but once detectives showed up there, he says he turned himself in.

"To set the record straight, I didn't have anything to do with it," Grant said. "I just didn't want people coming back on me thinking I did it and I just didn't want to be on the news or the person they focused on saying, 'I found the body.' "

He later added, "I was looking for some clothes that got thrown out there near where I found the body at, and I grabbed a tent pole and I started looking and lifted up the branch, and then I seen (sic) the body, seen the spine first, and it looked like an animal. And then I looked closer, and I see a head. It was a skull actually."

He was asked, "When you first found the bones, did you think it might be Adre'Anna Jackson?"

"At first, I thought it was an older man, actually (based on) the teeth and the dental work that had been done," he replied. "I asked people if they knew if she had any dental work done, and everybody said, 'no' that I talked to. If it was, I'd have shown them the body....tell them it was her...she was there. But it was only a spine and a skull that I could find."

Grant adds that he did help walk police through the exact spots where he found her body.

"I took them around the field a couple places that they hadn't been yet."

Police are holding Grant in the Pierce County Corrections Center in Tacoma. He is not charged with any crime related to Adre'anna's death.

And, police have made no arrests in the case.
