MARATHON, Fla. (AP) - A man is charged with threatening to blow up a Florida Keys post office.
 
The Monroe County Sheriff's Office says 69-year-old Juan Zigler handed clerks at the Marathon post office a garbled note Friday that threatened to blow up the Keys. They say he then threw an object over the counter that clerks thought might be a firecracker.
 
When deputies arrived, they arrested Zigler. The object appeared to be a battery with a wire attached to it.
 
Zigler was charged with making a false bomb report and delivering a hoax bomb and released.
