OKLAHOMA CITY -- Bethany Police have tracked down a key witness in the Carina Saunders murder case.
Saunders, 19, was murdered and dismembered last year.
Her body was found in a duffel bag in a Bethany grocery store parking lot.
Bethany Police are investigating the murder.
Detectives have been desperately searching for the most important piece of evidence in the case; a hard drive containing video of the torture and murder of Carina Saunders.
News Channel 4 sources confirm there is at least one person in Oklahoma City who may be willing to lead police to the video and she has spoken with detectives about the case.
Police have named a number of suspects in the slaying.
So far, only one suspect, 37-year-old Luis Ruiz, has been arrested on a charge of murder.
The woman who spoke to police about her knowledge of the murder now fears for her life.
She is afraid of retaliation from the people responsible for Carina Saunders' death.
The police informant is an admitted prostitute who primarily advertises her services online.
Several weeks ago, she contacted Scott Adams, one of Oklahoma City's high-profile defense attorneys.
"I convinced her to cooperate with police. They actually brought her to my house to sit down and talk. I told her this was the right thing to do and that they would protect her," Adams said.
Although Adams is now furious Bethany Police Detectives failed to file a recent search warrant under seal, essentially releasing the informant's name and personal information to the public.
News Channel 4 is intentionally withholding the informant's name from this report out of concern for her safety.
Adams believes his client's life is now in danger because she cooperated with police and they did not protect her identity.
According to News Channel 4 sources, the woman's information is very credible.
"I sat in on her interview and I believe everything she said," Adams said of his client's graphic, detailed account of the Saunders' torture. "It's pretty horrific. And to think that something like that goes on in Oklahoma City is disgusting and very scary."
The informant described a world where women are bought and sold for drugs; a world where those who misbehave, like Carina Saunders, are tortured and killed as a warning to others.
Scott Adams has not seen a video of Saunders' murder but his client told police that she has.
"I think what was so chilling to me was when she was describing everything (to police). I'm not going to get into detail but I've done this for 20 years and I've never heard of anything like this," Adams said.
Adams has no confirmation if the video actually exists.
Police have not confirmed if such a video exists or if they've located the hard drive where it's stored.
Based on his client's interview with police, Adams believes there will be many more arrests of people with involvement in Saunders' torture, murder and dismemberment.
Bethany Police will not comment on the existence or location of video footage.
In fact, they did not return our call regarding the Saunders' case.
Scott Adams has requested the help of an Oklahoma City non-profit organization to help his client, the informant, go into hiding for her own safety.
