LOUISVILLE, Ky. (WDRB) -- Hundreds of murderers are still on the loose, and the Louisville Metro Police Department is determined to put every single one behind bars.

Louisville homicide detectives are currently working more than 450 cold case murders. Some of those cases are decades old, but police say one tip from the public can often help solve a case.

In May 2005, Tyrone Cheatham was stabbed to death outside an apartment on Sebree Lane in the Norfolk neighborhood. His family still does not know who did it, why or even how.

"We're still hoping and praying that something will come up," says his mother, Sandra Cheatham, who has been hoping for closure for eight years since her son's murder.

"I think that was the worst day of my life."

Cheatham's case is one of 459 cold case murders under investigation by Metro Police.

"An eight-year old case -- those leads have drawn up -- I mean nobody is calling in leads anymore unless we get it out there that we're looking for leads on certain cases," said Sgt. Donny Burbrink III, head of LMPD's homicide unit, which oversees homicides, cold cases and missing persons reports.

Burbrink says any case can be solved with the right tip, even the ones dating back decades.

"Sometimes it's just that one small tip that will break open a case."

And that's why Sandra Cheatham still has confidence something will happen with her son's case.

"I still believe that it will be solved one day whether it's in our time or not," said Cheatham.

Anyone with information on the Cheatham case or any other murder can call the anonymous police tip line at 574-LMPD.
