The Lake County Coroner's office said Tuesday the autopsy was completed but additional tests could take several months.

A family member found Norris unresponsive and frozen Thursday as temperatures reached only into the teens. Police don't know yet if his death is weather-related.

According to The News-Herald of Willoughby (bit.ly/1hIxCdl), Detective Sgt. Brian Jackson says police don't suspect foul play, but nothing has been ruled out.
