WI Inmate Sentenced In Bomb Scare Against Scott Walker

MADISON, MN — A 53-year-old state prison inmate was sentenced last week to three years of incarceration for his role in a 2018 bomb scare threat against then-Gov. Scott Walker.

Terrance Grissom pleaded guilty as a habitual criminal on Dec. 7. His latest sentence will run consecutively with his previous sentences, which are also related to making threats against government officials.

Grissom is not eligible for parole until Dec. 6, 2036, according to the Wisconsin Department of Corrections.

"Those who make criminal threats to harm others must be held accountable," said Attorney General Josh Kaul in a statement. "Bomb scares are serious offenses, and I’m thankful to everyone involved in the investigation and prosecution of this case."

On April 9, 2018, a letter was mailed to the Dane County District Attorney’s Office from Grissom in prison, investigators said. The letter stated that there was a bomb in the governor’s office that would go off at the push of a button and the governor would die.

Capitol police officers evacuated the governor’s office, the lt. gov.'s office and the attorney general’s office in the Wisconsin Capital building.

A bomb-sniffing canine was brought in and it was determined there was no threat, police said.
