WEST PLAINS -- A preliminary hearing was held June 11 in U.S. Federal Court in Springfield for Donald Schamber of Mountain Grove.
Chief Federal Magistrate James C. England found probable cause to send Schamber's case to trial.
Schamber, 60, is in federal custody in Springfield charged with mailing a package containing explosives, a pipe bomb, with the intent to injure people.
The package was addressed to the West Plains Police Department. Schamber reportedly told West Plains Police he sent it to try to get his ex-wife's current husband in trouble.
A postal inspector said anyone opening the package could have been killed or seriously injured.
The package was discovered June 1 at a mail dropbox in the parking lot at the Parkway Shopping Center. It was intercepted by postal employee Carl Farruggia who thought the package looked suspicious. The package did not have a return address and had 10, 41-cents stamps on it.
The ?Missouri State Police Bomb Squad from Jefferson City was called to the police station where postal inspectors had left the package. It was X-rayed and determined to be a functional explosive.
Schamber turned himself in to West Plains Police and confessed to building and mailing the bomb in an effort to cause trouble for Tom Bush of West Plains, so Schamber could start a relationship with Bush's wife, Schamber's ex-wife, Carolyn.
It is not known what connection, if any, Bush had with the West Plains Police.
If Schamber is found guilty he could spend 50 years in federal prison and pay a maximum fine of $250,000.
No trail date has been set.
