BERKELEY -- A man was found dead in the Berkeley hills Wednesday evening, but the way he died remains a mystery.

According to the Berkeleyside website, the man, who was in his 20s, was found roughly 200 to 250 feet downhill from Grizzly Peak Boulevard on UC Berkeley campus property after being reported missing by a friend earlier in the day.

Berkeleyside reported that around 6:29 p.m., UC police received a call from the California Highway Patrol informing them of a missing person report. UC police offered to assist and officers found the missing man downhill of Grizzly Peak Boulevard near Signpost 15.

The young man was identified by the friend who had reported him missing. Berkeley Fire Department declared him deceased at 7:22 p.m, according to Berkeleyside.

The website reported that UC police are treating the incident as an unattended death and that no vehicles were involved. Police also stated the man was not affiliated with UC Berkeley, and a large rock found nearby led police to speculate if the victim may have struck it.

The location where the man's body was found is in UC Berkeley's jurisdiction and is in the city of Oakland.

Police are currently investigating the case and said updates will be provided pending any developments.
