BISMARCK, N.D. -- Mandan police said they put in a call to the Bismarck bomb squad after a 70-year-old woman turned in a munition shell she had found among her late husband’s effects.

The Bismarck Police Department bomb squad, in turn, notified the Minot Air Force Base, Bismarck Police Sgt. Mark Buschena said. The air base’s explosive ordinance disposal team said the device had no potential for explosion.

The M29 practice rocket was “rendered unserviceable,” Air Force spokeswoman Maj. Davina Petermann said.

The Minot Air Force Base team came to Mandan to X-ray the rocket and confirmed its initial suspicion there was no danger of an explosion.

Petermann said the rocket was taken to Minot and disposed of, though she could not comment on the method of disposal.
