Earlier: Niles man died in California
Patch had earlier reported a Niles man was found deceased in his vehicle Saturday afternoon, Nov. 24, at a scenic overlook in Joshua Tree National Park in southern California.
The man was later identified as Slepowronski, according to the Press-Enterprise.
Niles Police Sgt. Robert Tornabene said Slepowronski's mother reported him missing Nov. 12, and the department stayed in contact with the family as they tracked his movement westward via his credit card usage.
The mother told police her son had left and taken off for the West before, when the mood struck him, Police Chief Dean Strzelecki said.
The Riverside County, Calif. coroner's office did not have a cause of death as of Friday. It will not be known until toxicology reports, which could take as long as five to six weeks, are completed, they said.
