FLINT, Mich. (Michigan News Source) – A Michigan man who declared “death to you all” and mapped out a mass killing spree will spend the next seven years behind bars after federal authorities shut down what prosecutors say could have been a deadly attack.

A blueprint for chaos.

According to a recent press release from the United States Attorney’s Office, Eastern District of Michigan, Mack Davis, 23, of Owosso, pleaded guilty to a federal hate crime after investigators uncovered detailed plans for a mass-casualty attack.

He compiled lists of weapons and tactical gear and scouted multiple locations – including churches, synagogues, mosques, schools, hospitals, and supermarkets – as potential targets. His writings made his intent unmistakable, expressing hatred toward all people and signaling a willingness to “fire on anyone and anything” in his path.

Targets and twisted motives.

Authorities say Davis also fixated on specific locations he believed would be frequented by LGBTQ individuals, including a political party office and a nearby bar. His online activity and personal writings showed a disturbing fascination with past mass killers and extremist ideology.

Stopped before it started.

Authorities were able to stop the planned attack because they stumbled onto the suspect’s actions early and moved fast. Investigators began looking into Davis after he fired dozens of rounds into nearby vehicles and posted disturbing, hate-filled material online – red flags that triggered a deeper probe. That investigation led to a search of his home, where law enforcement uncovered a stockpile of weapons, ammunition, and bomb-making materials, effectively shutting down the plot before he could carry it out.
