Former Iowa professor, a Marion man, sentenced to 7 years for dealing meth

After arrest, he threatened couple he thought set him up

CEDAR RAPIDS — A Marion man, who is a retired Iowa college professor, was sentenced Wednesday to more than seven years in federal prison for distributing methamphetamine.

Randall Mark Gilbert, 61, pleaded in July to possession with intent to distribute methamphetamine near a protected location — Lisbon High School. During the plea hearing, Gilbert admitted that on April 4 he had more than 10 grams of meth while he was within 1,000 feet of the high school. 

After police obtained a search warrant for his home, officers found 13.16 grams of meth with a purity of 100 percent, court documents show. During an interview with police, Gilbert admitted selling meth.

After arrest and release from jail pending trial, Gilbert on April 5 went to the home of a man and woman he thought set him up. The man ran out of the house during the confrontation, and then Gilbert cut a phone line and threatened the woman with a knife. He forced the woman to go with him to his house and threatened to beat up the woman and the man.

U.S. District Judge C.J. Williams sentenced Gilbert to 85 months in prison and ordered him to serve eight years of supervised release following his prison term.

Gilbert will remain in custody with the U.S. Marshals Service until he is transferred to a federal prison.

Gilbert was a former college professor in Iowa.

The case was prosecuted by Assistant U.S. Attorney Emily Nydle and investigated by the Lisbon, Mount Vernon and Mechanicsville police departments, the Cedar County Sheriff’s Office and the Jones County Emergency Response Team.
