Third Bomb Arrest For Grand Junction Man

Robert Del Johnson faces more bomb charges.

Back in 2009, Johnson was arrested and charged with a felony count of possession of explosives or incendiary devices and a count of interference with a school. He had been accused of planning a Columbine-type attack on Palisade High School.

He was sentenced to two years at Community Corrections.

Two years later, in 2013, Johnson was arrested again. His friends had tipped off police that he was going to build pipe bombs to 'kill everyone.'  He was charged with one felony count of explosives or incendiary devices and a misdemeanor illegal weapons possession count. Johnson was sentenced to three years probation.

Now, he faces a third set of charges dealing with bombs and explosives. Investigators from the Western Colorado Drug Task Force searched his residence and another home in his name, they found two homemade pipe bombs, assorted bomb-making materials, a disassembled shotgun shell and metal BBs mixed with black powder.

Two counts of possession of explosive or incendiary devices and a single count of weapons possession by a previous offender await Johnson when he returns to the Mesa County Courthouse on Tuesday, January 3.
