COLLIER COUNTY, Fla.- The Collier County Sheriff's Office is still trying to find out who killed 48-year-old Joseph Godcharles  on August 1, 2012.

The drugstore manager was found slain inside his apartment at 8234 Key Royal Circle #511 in the lakefront Key Royal Villas community, off Immokalee Road, east of I-75.

CCSO is marking the two-year anniversary of Godcharles' death by asking the public for help with identifying his killer.

His body was discovered in the master bedroom. He had been stabbed multiple times with a knife.

Detectives said the condo was found unsecured by Godcharles' son, who contacted law enforcement, and there was no evidence of a burglary, indicating Godcharles may have known his killer.

Detectives believe Godcharles was killed sometime between 8:24 p.m. on July 31, 2012, the time he punched in his code to enter his gated community, and 9:16 a.m. Aug. 1, 2012, when deputies were dispatched to the scene.

Detectives have been following up on tips and leads during the investigation, but what they need is a witness who can place a suspect in the vicinity of the crime during that time frame.

Detectives believe someone has information about the case that could give them the break they need to make an arrest.

Anyone with information about this case, please contact Detective Steve Spell at (239) 252-0056, or Crime Stoppers at 1.800.780.TIPS (8477).
