REED CITY\u00a0\u2014 A man\u00a0was arrested\u00a0after pulling a weapon on a doctor while\u00a0possibly under the influence of drugs at a Reed City hospital. Rodney David Koepnick, 41, of Reed City, is charged with three counts of felonious assault, one count of aggravated indecent exposure and one count of\u00a0assaulting\/resisting\/obstructing an officer. Troopers from the Michigan State Police Mount Pleasant Post were dispatched at 5:20 p.m. Saturday to a reported disorderly male at Spectrum Health Reed City Hospital. The suspect,\u00a0Koepnick,\u00a0who is a\u00a0registered\u00a0sex\u00a0offender, reportedly exposed himself to\u00a0hospital staff, then\u00a0forcibly removed\u00a0his IV and medical equipment. When contacted by the\u00a0emergency\u00a0room\u00a0doctor, the suspect pulled out a folding style pocket knife and brandished it in a threatening manner at the\u00a0doctor and two other\u00a0staff members.\u00a0At the time of the incident, Koepnick was\u00a0believed to be under the influence of methamphetamine. Koepnick\u00a0then fled from the\u00a0hospital on foot. Troopers\u00a0located\u00a0him\u00a0running\u00a0northbound on 220th Avenue away from the\u00a0hospital. Despite observing the fully marked patrol car and numerous verbal commands from troopers to stop, Koepnick\u00a0continued to flee on foot. After a short chase,\u00a0he\u00a0was cornered on the\u00a0west shoulder of 220th Avenue and taken into custody without further incident. Police recovered\u00a0the weapon involved from Koepnick\u00a0after his arrest.\u00a0Troopers were assisted on scene by the Osceola County Sheriff's\u00a0Office. Felonious assault, also known as as assault with a dangerous weapon, is a felony punishable by up to four years in prison. However, Koepnick faces twice the maximum penalty because of prior convictions. Koepnick was arraigned Monday in Osceola County's 77th District Court. His bond was set at $100,000. A preliminary examination is set for 1:30 p.m. on Thursday, March 1, in district court.
