Jeremy Reid Johnson, 50, of Austin pleaded guilty to felony second-degree assault with a dangerous weapon as part of a plea agreement on Monday in Mower County District  Court. He initially pleaded not guilty to the charge on Feb. 8.

Charges of felony terroristic threats and felony false imprisonment were dismissed.

Johnson was arrested on Nov. 15 at Jim’s Supervalu after coming up behind a 17-year-old cashier and holding a pair of scissors to her throat and chest area. Austin Police Chief Brian Krueger said that multiple witnesses called the police and reported the situation.

Law enforcement agents established a perimeter and ordered Johnson to let her go. The cashier was eventually able to get away from Johnson and ran to the back of the store.

Officers then arrested Johnson and retrieved the scissors he held to the cashier’s throat, Krueger said.

Johnson told officers he had ingested plant food, a type of synthetic drug, before the incident, according to Krueger.

A review of Johnson’s criminal history shows prior convictions for assault, criminal damage, terroristic threats, making obscene or harassing phone calls and check forgery.

Johnson will be sentenced on Jan. 18.
