Mann is accused of threatening federal employees in Warren, the indictment says

(CBS DETROIT) – A former employee of the US Army Tank-Automotive and Armaments Command (TACOM) in Warren is facing charges for making threats against employees of the command.

Court documents show that the man is accused of sending threatening messages.

According to the criminal complaint, the man worked as a contract specialist for the Warren facility for 18 years but was fired in 2015 after multiple violations.

In 2019, a package containing a doll's head and a threatening letter was sent to the man's former supervisor, the complaint says. FBI agents interviewed the man who admitted to sending the package and said he would never threaten anyone at TACOM again.

In March, a suspicious letter was sent to the command. According to the complaint, it included the phrase “death card” and the names of five TACOM employees, including the man’s former supervisor. The handwriting on the letter matched the 2019 note.

FBI agents re-interviewed the man, who admitted to specifically targeting the people he believed were responsible for his firing, the complaint says. The man said he was accused of signing something he didn't do and they destroyed his life.

The man told agents the letter was intended to scare employees but said it would not hurt anyone, the complaint says.

The man was shown a copy of the letter and envelope it was sent in and confirmed it was the letter he had sent, according to the complaint.
