A 26-year-old Lincoln man has been arrested, accused of sending threatening emails and graphically violent pictures to a Nebraska Department of Labor employee.

The man was arrested Thursday on suspicion of making terroristic threats, stalking and third-degree assault.

In court records, the Nebraska State Patrol described one email in which he questioned her description of him as a “job hopper,” then threatened to “slaughter you like a (expletive) cow.”

Investigators say the email included four images of severely mutilated female body parts.
