LINCOLN, Neb. (AP) — A former guard at Tecumseh State Correctional Institution accused of trying to smuggle drugs to inmates has been sentenced to 18 months of probation.

21-year-old Michael Splittgerber was sentenced Monday. He pleaded guilty in August to conspiracy to convey an article to a committed offender.

Prosecutors say Splittgerber offered to sneak marijuana into the prison to an inmate in May 2014.

According to an arrest affidavit, prison officials learned of the offering when an inmate reported to Splittgerber’s superior that the guard told the inmate he had something for him. Authorities say a search of Splittgerber’s pockets by prison officials turned up marijuana inside a staff-issued plastic glove.

Splittgerber worked for the Department of Correctional Services from December 2013 to June 2014.
