HOUSTON – A Texas prisoner has admitted he killed one of the young women whose body was dumped in the so-called "Killing Fields" of League City. 

Behind prison walls, behind thick glass of a visitation room, Mark Roland Stallings is clear and convincing in his account of what happened 25 years ago.

"I'd walk out there right now and point straight at where she was," Stallings said.

I-Team: "You knew from the moment you picked her up?"

Stallings: "Exactly, when I picked her up I knew what I was going to do."

Stallings had picked up the young woman on Telephone Road near Interstate 610. He described her as "trashed," "wasted," with "skin barely over her bones" and "emotionally gone." He said they went to a motel and did some drugs.

"And I said, "Look, you know, let's go for a ride,'" Stallings said.

That ride took them south to League City and a field off Interstate 45 and Calder Road. It's where Stallings once worked as a ranch hand, and where three bodies had been discovered in the 1980s. The young woman with Stallings would be the fourth in the Texas Killing Field.

"I ended up getting the seat belt and hit her in the head with the seat belt buckle, right, and then wrapped the seat belt around her neck and choked her out," Stallings said.

I-Team: "Choked her out meaning…"

Stallings: "Choked her out you know."

I-Team: "You killed her."

Stallings:  "Yeah."

The decomposed body was found months later in 1991. Authorities have never been able to identify the woman. She is known only by an artist's rendering as Janet Doe.

But it wasn't the first time Stallings admitted to killing Janet Doe. Jim Carroll is an ex-con who exchanged letters with Stallings for more than two years. Between December 2013 and January 2016, the two wrote more than three dozen letters back and forth.

"I know I had no right to take this young girl's life; she was just an innocent girl," Carroll read from one of the letters.

For Carroll, Stallings' tone is clear.

"I think he's trying to clear his conscience, because he knows he's not going to get out," Carrol said.

Stallings, 50, is serving more than two life sentences for unrelated crimes, including aggravated kidnapping for a 1998 escape attempt while in prison.

If he is, in fact, clearing his conscience, he's doing so in great detail. During the interview, Stallings pointed out the location of Janet Doe's body on a map he had drawn for Carroll.

"There she is right there. That's exactly where I put her, exactly where I put her," Stallings said.

But to this day, Stallings has not been charged in the murder of Janet Doe.

"Texas has convicted people for less than this," Carroll said. "Indict him!"

It's not that simple, according to investigators at the League City Police Department.

"Just because somebody says they did something doesn't always give us ammunition to go to court," said Detective Marty Grant.

Grant was one of the original detectives on the Janet Doe case. In 2001, he questioned Stallings over five days at the scene and said the suspect confessed back then, too. But Grant said Stallings later recanted. Now his story is changing again.

"Some of the things he told you does not corroborate some of the things he told me all those years ago," Grant said.

The inconsistencies throw even more questions into the mix, and add to the mystery of the Texas Killing Fields.

"I shouldn't have did (sic) what I did," Stallings said.

"I mean even though she was in the condition she was in, I should have just let her play her own life out, you know she wanted to waste it and I should have just let her waste it," Stallings said.

As for the other three victims, Stallings denies every killing them and League City Police said they continue to build a case on another suspect in those murders.

Grant said investigators plan to pay Stallings a visit in prison, with the hope he will once again talk about what happened to Janet Doe.

Police are also still working on trying to identify Janet Doe and are asking for help. They do have DNA and can make a match. Click here for more information about Janet Doe and who to contact if you think you may know who she is.
