(KLZA)--A former inmate at the Tecumseh State Correctional Institution, who authorities say allegedly planted a faculty bomb outside the prison was shot and killed by troopers in Montana near the community of Big Timber on April 3.

27-year-old Breighton Miller was imprisoned following a 2019 conviction for first-degree sexual assault which involved a 15-year-old girl in 2018.

A warrant for his arrest had been issued after an apparent bomb was left in Tecumseh prison's parking lot.

KOLN-TV in Lincoln reports that on the morning of April 1, two employees at the prison spotted two propane tanks left near a truck in the parking lot .

One tank's valve had been opened, and a spent road flare was next to it. The vehicle belonged to a captain at the prison.

According to an arrest affidavit, surveillance video from the parking lot at the prison, spotted someone leave the propane tanks and flare a few minutes prior to their discovery.

The suspect left in another truck, and it was later found to belong to Miller.

Prosecutors charged Miller with one felony count of placing a false bomb on April 3. Troopers in Montana ran into him the same day in the middle of the state.
