SEATTLE -- Improved DNA technology has put an 18-year-old cold case double-murder back into "active status," and we have some incredibly unique undercover videotape to prove it.

In January 1990, a neighbor found Seattle attorneys Eric Hoyer and Steve Dorobis shot dead inside a house they shared in South Park.

Investigative Reporter Chris Halsne discovered King County detectives are currently questioning a former University of Washington football star regarding the killings.

Halsne said, "Our investigative unit has been retracing every aspect of this crime for nearly two years. One famous name keeps popping up: Robert "Spider" Gaines. He was a wildly popular receiver at the UW in the mid-1970s. Gaines denies there is any evidence that links him to this crime. We tracked down an old roommate of his who is telling a different story."

Spider Gaines' speed and strong hands made him a star in purple and gold. Whether it be hauling in long touchdown passes from now Hall-of-Fame quarterback Warren Moon or grabbing big catches in the '78 Rose Bowl on national TV, Gaines was always the center of attention.

Friends say when the cheers subsided and an injury shortened his professional football career, Spider had a tough time adapting.

In the 80s, he turned to a life of alcohol, drugs and trouble.

Until now, few knew how much trouble.

Coffee Williams is a 50-something-year old petty thief with a nagging drug habit. She lived with Spider Gaines at a South Park home back in 1990.

She told KIRO Team 7 Investigators, "He (Spider) seemed like he was always on the edge."

The two of them lived only about six blocks from the scene of an unsolved bloody double murder.

Attorney Eric Hoyer was executed, shot once in the back of the neck in the kitchen/dining room area. His roommate, Steve Dorobis, died from multiple gunshot wounds, still sitting on his bed.

Williams knows police are looking at her and Spider Gaines as suspects.

"Yeah. The rumors were that me and Spider killed those two people, that me and Spider did it. It wasn't me. They (the victims) didn't do nothing to me. I had no reason to go to those people's house and do nothing to them."

Williams agreed to conduct a pair of interviews with KIRO Team 7 Investigators after we discovered that forensic evidence might place her at the scene of the crime.

"I know he had been there. I know I had been with him."

The "him" is Spider Gaines. She says she drove the former UW football star to the attorneys' home just prior to the murders to collect a debt.

Williams told Halsne, "Once we got there, Spider told me to just stay in the car, that he'd be right out. He had to go in to see if these guys had his money. I can't really say Spider killed those people, ya know, because I was outside in the car. It was maybe a couple days later and they showed a picture of a helicopter on top of a house, most likely the news people on the house. That's when they said two lawyers had been killed in this house. Shot to death. I looked and I realized it was the house that he had went to."

Police believe Williams knows a lot more, and that was apparent during our interviews. She knows the layout of the attorneys home and details of the crime scene never released.

For example, Williams told Halsne, "The other guy wouldn’t have got killed, but he came out of the room."

Williams admits to us, police starting calling her a suspect in 1993 and have never stopped.

A cold case homicide file obtained by KIRO Team 7 Investigators, confirms that and more. In 1993, former King County homicide detective Earl Tripp wrote "there is every reason to believe that Robert "Spider" Gaines and Coffee Williams were involved in the murders." Recently, he spoke with KIRO Team 7 Investigators on the phone from Arizona. He says Spider Gaines was, and as far as he knows, still is the prime suspect in the attorney's deaths.

Coffee says she may have been at the house at some point, but was not inside the night of any murders.

"I wasn't in the room. I wasn't in the house. Not with him. Know what I'm saying. Whatever happened, happened."

There should be no doubt police think Williams is important. After learning about our interviews, detectives and a prosecutor asked to look at the tape -- to which we agreed.

Then just two weeks ago, while KIRO Team 7 Investigators were conducting undercover surveillance on Spider Gaines as part of our investigation, two cold case homicide detectives showed up to speak with Gaines outside his workplace.

The pair of detectives flanked Spider in a parking lot, while they spent a total of 45 minutes speaking with the former UW star, whose silhouette is unmistakable at 6 feet 4 inches tall and 240 pounds.

Despite our videotape proof of King County's interest in Gaines in connection with a double murder, Sheriff spokesperson John Urquhart, says he is not comfortable publicly naming suspects.

However, he confirmed to us that cold case detectives very recently sent some "trace evidence DNA" collected from the crime scene to the lab for analysis.

"We did develop a couple of really good suspects. They remain suspects to this day. At this point, we don't have enough information to charge them and we're not comfortable arresting them just yet. These people remain suspects today. They have not been cleared. We have not been able to clear them in this case."

On the phone last year, Spider Gaines told us he has turned his life around and is doing charitable work helping teach kids about fitness. He added that "there is no evidence that links him to this crime."

Here is an exchange between Investigative Reporter Chris Halsne and Robert "Spider" Gaines, videotaped January 31, 2008:

Halsne: "Hi. My name is Chris Halsne. I'm an investigative reporter at KIRO-TV."
Gaines: "Uh-huh."
Halsne: "I talked to you not that long ago about police having you be a suspect in that double homicide down in South Park . I hear things are heating up a little bit and they came and saw you. Can we talk about that? Tell me what they asked you."
Gaines: "First of all, I really don't want to talk about that. Ya know. I'd really appreciate it if you'd leave me alone."
Halsne: "I understand, but we want to make sure we give you every opportunity to counter what the police are telling us, which is that you are the prime suspect in that homicide."
Gaines: "I don't care what they're telling you. I ain't worried about it. They can say whatever they want to say. Leave me alone. I'm outta that."
Halsne: "When we talked earlier, you encouraged me to track down Coffee Williams). We did. She had an interesting story. Can we talk about what Coffee is saying?"
Gaines: "No. Nope. Nope. I'm not even worried. Nope. Leave me alone. I'm going to work."

Gaines also told Halsne, homicide detectives came to his house years ago and asked him to take a lie detector test. Gaines declined.

Police records show Coffee Williams agreed to a polygraph.

Sources inside both the Prosecutor's Office and Sheriff's Department tell Halsne that Williams passed questions about "being there" (at the murder scene), but failed when it came to questions about the depth of her involvement.
