Knoxville (WVLT) -- Sunday would have been Johnia Berry's 24th birthday.
Instead, her killer has gotten away with her murder for more than two and a half years.
So her family and friends are marking this weekend, by asking us not to forget Johnia.
They, and other volunteers spent much of Saturday working out of Church Street United Methodist Church and various Knoxville neighborhoods to pass out flyers.
Knox County Sheriff's investigators say they've interviewed more than 900 people, and taken more than 350 samples of DNA, but there is still no named suspect.
"All of the DNA is back now, and you know there was nothing turned up from that. You know, it's kind of a dead end right now.
There's no new leads and that's really scary," said Joan Berry, Johnia's mother.
Investigators don't use the word cold case, but family members like Joan tell us they don't know what else to call it.
"Somebody somewhere knows something," she said. "I mean they have to, you know that somebody has to know something. I think it's just a matter of finding the right person and that they find it in their heart to help."
Johnia was found stabbed to death in the breezeway of her West Knox County apartment in December 2004.
Her room-mate survived the attack.
The sketch of a possible suspect, is a man he described.
