911 caller made bomb threat before Rice Lake, Wis. apartment explosion

A man called 911 in Rice Lake, Wisconsin late Sunday night and told the dispatcher he had a bomb. A short time later, an explosion and fire destroyed his apartment building.

The Rice Lake Police Department first responded to the 911 call at 11:07 p.m. Sunday. Upon arrival, officers approached the South Main Street apartment of 44-year-old Joseph Zunker and heard a man yelling inside.
