A corporal at the Nebraska State Penitentiary in Lincoln was caught Saturday trying to bring contraband into the prison, spokeswoman Dawn-Renee Smith said.

Michael Miller, 24, was arrested and taken to the Lancaster County jail. He is charged with bribery and unauthorized communication with an inmate.

A search of his vehicle turned up the illegal substance known as K2. Miller told an investigator that his intention was to sneak K2 inside to an inmate, Renee Smith said.

Unspecified workers at the penitentiary thwarted his attempt.

Miller was hired at the penitentiary on Aug. 26, 2016 as a corrections officer. He was promoted to corporal on May 1.

He is currently suspended without pay.

Nebraska Director of Corrections Scott R. Frakes said it is disappointing to see staff members make choices to break the law and endanger the safety of their coworkers and inmates.

“The side effects of K2 pose a significant risk to the user and can result in violent behavior, which also puts my team’s safety at risk,” Frakes said. “We will continue to employ security measures in our prisons to prevent the introduction of contraband and keep people safe.”
