Police are investigating the death of a man found dead Wednesday night in a home in south DeKalb County.

Officers performing a "welfare check" at the home on Shell Bark Road, in a neighborhood off Miller Road, found the 50-year-old man dead inside the house just after 8 p.m., according to DeKalb police Lt. Jerry A. Lewis.

Police have not released the man's name or disclosed how he died, but Lewis said the death is "suspicious in nature."

He said investigators have no suspects in the case.
