John Herren, 40, walked into his workplace, the civil engineering firm Dale & Associates, in Berry Hill, Tenn., carrying two knives, walked behind his supervisor’s desk allegedly grabbed his head and slashed his throat, The Tennessean reported, citing an affidavit.

The alleged attack occurred at about noon.

The supervisor and Herren both ran out of the office, the newspaper reported. Herren took the knife he allegedly used but dropped a second knife.

Berry Hill Police reportedly recovered the dropped knife.

Doctors treated the supervisor at a nearby hospital for “superficial lacerations on his throat,” the Tennessean reported, adding that emergency medical services noted that the outcome could have been a lot worse since the cut was very close to a main artery.
