Juan Sigler, 69, charged with threatening to blow up a Marathon post office

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 Sigler 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 Sigler. The object appeared to be a battery with a wire attached to it.

Sigler was charged with making a false bomb report and delivering a hoax bomb and released. No phone number for Sigler could be found Saturday.
