WARREN, Ohio - Warren police are investigating the city's fifth homicide of 2013. Detectives say they're investigating the apparent beating death of Donald Jones Sr., 56, of Warren.

Officers responded to reports of a foul odor coming from a home at 1003 Hemlock Ave. SW after a call was made to 911 dispatchers Thursday, at about 3:30 p.m. 

Inside, they discovered Jones' body partially decomposed.

No one else was in the home at the time. Police say his cause of death was blunt force trauma.

On Friday, the department continued to investigate what happened.

"There was a call that came into 911 dispatch by an anonymous caller, which is pretty much part of our investigation-- that's where we're going to start," Lt. Jeff Cole says, department detective.

On the 911 call, the dispatcher can be heard describing the caller as "very uncooperative", a man, that eventually hung up the phone.

Neighbors describe Jones as a man who kept to himself.

An autopsy is scheduled to be performed in Cuyahoga County.

Cole says they have no motive, suspects or persons of interest at this time.
