ATLANTA -- Gary Hilton admitted to Georgia Bureau of Investigation agents what most Georgians already assumed -- the calculating killer was a loner detached from almost everything.

“I’m a sociopath man. I’m what they call an anti-social,” Hilton told GBI agents.

For the first time, the Georgia Bureau of Investigation has allowed Channel 2 access to its entire case against Hilton, who is serving a life sentence for murdering hiker Meredith Emerson.

Channel 2’s Jodie Fleischer spent the day going through four hours of interviews with Hilton right after his guilty plea in the Emerson case.

The tape is different from past tapes. First, because it’s video you can see Hilton’s movements and what gets him worked up. But also because it doesn’t completely focus on the Emerson murder – it instead shows how agents were trying to use Hilton to uncover information in other murders, including the three he’s already suspected of and any others that may still be unsolved.

"You could take me to the front door of this jail and say go forth and sin no more. I would literally have to turn back around and walk back in here,” said Hilton.

He refers to his behavior as a rampage and appears to admit he’s killed more than once.

"If you're already caught there's no use in killing them. I didn't kill them because, for any satisfaction,” said Hilton.

He’s suspected in the murder of a North Carolina couple in October and a Florida woman in December. She was found in the Apalachicola National Forest, which Hilton smugly references.

“You can go down to Apalachicola Forest for that matter (laughs)," said Hilton.

And he caught on as agents tried to chart a timeline of his whereabouts. On the tape, an agent asks where he’s been in the United States and Hilton said, “Oh, I know what you’re getting at…the unsolved murders.”

In one instance, Hilton did show fear when presumably referring to the North Carolina case already in the hands of Federal prosecutors. Hilton appears in the background of a photo the night before the Emerson kidnapping. The yellow jacket with reflective tape appears to match the one in the photos from an ATM where the North Carolina couple’s card was used.

“I'm telling you right now, I'm going to dig my heels in. I don't want federal custody. They're going to send me to super max I know they are,” said Hilton.

Hilton called himself a hunter and a professional. The rapport and trust built by the GBI agents is evident in the tapes.

“I promised you cooperation that night, I gave it to you. The only question I didn't answer was on the advice of my attorney and I would have answered that,” said Hilton.

That question? How many people has he killed?

The GBI did black out several sections of the tape which directly refer to the North Carolina or Florida cases.

Hilton is still in Georgia serving a life sentence. He has already begun fighting his extradition to Florida.
