Prosecutors: Man to plead guilty on post office pipe bomb

HAMMOND, Ind. (AP) — Federal prosecutors say a man charged in a pipe bomb explosion at a northwestern Indiana post office has agreed to plead guilty and serve a 29-year sentence.

They announced Tuesday that 46-year-old Eric Krieg of Munster has signed an agreement indicating his intent to plead guilty to knowingly making an unregistered destructive device, mailing a destructive device, malicious use of explosive materials, and mailing a threatening communication.

They say Krieg is prepared to admit he mailed a pipe bomb on Sept. 6, 2017, that targeted an attorney and mailed a threatening letter to another person 23 days later. The bomb exploded at the East Chicago post office, injuring a postal worker.

Krieg has been in federal custody since his October 2017 arrest.

Prosecutors say a plea hearing will occur soon.
