BISMARCK, N.D. _ Charges have been dropped against a man accused of screaming and swinging a knife as he walked through downtown Mandan.
Nathan Siebrasse, 35, was charged with Class C felony terrorizing, Class C felony preventing arrest or discharge of other duties, Class B misdemeanor disorderly conduct and Class B misdemeanor failure to halt in the Feb. 9 incident.
Morton County Assistant State’s Attorney Gabrielle Goter said the charges were dismissed because of a doctor’s opinion that Siebrasse was not competent at the time of the incident.
Siebrasse gained some notoriety around Bismarck and Mandan last summer for skateboarding around the towns in wizard costumes.
Mandan police were called to the 100 block of East Main Street just before 1 p.m. on Feb. 9. A witness said a man had been screaming, swinging a knife and striking vehicles and mailboxes as he walked west.
A witness later told police the man, identified as Siebrasse, was yelling and threatening a woman with the knife as he got out of the vehicle she was driving. The woman then drove away. The witness said Siebrasse moved aggressively toward him and another man with the knife as they stood outside. Siebrasse put the knife away when the witness asked him to, he said, but the witness called 911 when he saw Siebrasse unsheath it again.
Authorities said Siebrasse walked toward an officer with the knife unsheathed and refused to stop when commanded, then ran when the officer drew his gun. The officer chased Siebrasse, and he ran into a First National Pawn. Siebrasse was holding a drill when the officer went inside the store. The officer used a Taser to get Siebrasse under control inside the store.
Goter said Siebrasse was taken to the State Hospital for a mental evaluation, and a doctor deemed him incompetent at the time of the offense due to mental and medical issues.
Siebrasse pleaded guilty on Monday to Class C felony theft and Class A misdemeanor possession of drug paraphernalia, in unrelated incidents. Goter said he was sentenced to all but time served suspended in both cases, with three years of supervised probation in the felony case and two years of supervised probation in the misdemeanor.
Goter said Siebrasse’s probation conditions include being required to take prescribed medications and make restitution in the theft case.
