Ex-Ohio doctor admits making pipe bombs that exploded in his apartment, changes plea to guilty

A former Ohio doctor has admitted keeping dozens of pipe bombs that were part of an arsenal seized at his apartment after two explosions.

Mark Campano of Cuyahoga (ky-uh-HOH'-guh) Falls near Akron pleaded guilty Thursday in Cleveland federal court to one count of possessing unregistered weapons. He had previously pleaded not guilty.

He could get 10 years in prison but is likely to receive less under sentencing guidelines.

The 57-year-old Campano was injured when two explosions rocked his apartment in November. Federal agents found 37 pipe bombs and two homemade gun silencers.

Medical board records show the former anesthesiologist has practiced in Ohio and West Virginia and has a history of substance abuse.

No motive was mentioned in court. Campano's mother says he never intended to harm anyone.
