Out of 800 vulgar voice messages believed left by Kentucky fans at the office of referee John Higgins, after UK's loss to North Carolina in the NCAA Tournament, seven are classified as a threat.

Sarpy County Sheriffs Detective Matt Barrall spent 80 hours reading posts and listening to voice messages, selecting the seven that might be considered a crime.

Detective Barrall tells WOWT, "There was some sort claim of violence, whether it be they wished him dead or wished him injured."

Laced with obscenities, the seven voice messages need extensive editing but clearly seek harm on referee John Higgins.

The threatening messages said:
#1 - "You should put a gun in your mouth and blow your won fricking brains out."

#2 - "If I ever see you in person I'm going to smack the taste out of your fricking mouth."

#3 - "You're going to pay buddy."

#4 - "You enjoy your life before somebody kills you."

#5 - "Hey you hear that garbage truck in the background? Wish you were in it personally you **."
