CHATTANOOGA (WRCB) --  Crime Stoppers is asking you to think back six and a half years ago, to the night a woman was last seen on Main Street.

Investigators are doing their best to fire this back up. They say Gina Muir was well known and they believe someone out there knows something that could help track down her killer.

"There's just not a lot to go on..." says Investigator Justin Kilgore.

Little evidence and now Kilgore is fighting the clock.

In November 2004 her skeletal remains were found wrapped in carpet, near an alley at East Main and Mitchell Avenue. The medical examiner determined she suffered blunt force trauma and had a fracture at the base of her skull.

"At one point I believe she was living in her car and not far from where she was found ... but definitely drugs, could've been drug related," says Kilgore.

Kilgore says 37 year old Muir had been living with her mother in 2004 but left after she was confronted about drug use. The last time she was seen was late March 2004.

"Generally when you find bones, there's nothing fresh, no fresh witness, no fresh suspect to talk to," says Kilgore.

That's why Kilgore is making a plea for anyone with any information to come forward.

"People out there knew her, what kind of lifestyle she had, people she had contact with,she had a lotta friends out there... People know something, says Kilgore.

Investigators have tracked numerous leads over the years, and have had very strong suspicions at times. They just need help finding a fresh trail.

"There's talk, some knows something they might be afraid to come forward or they may think the info is not important let us be the one to make that determination," says Kilgore.

It's time to get Gina Muir's murderer off the streets.
