John Michael Pekrun

Deadly force

Earlier that day, the state of Wisconsin issued a warrant for probation violation for John Michael Pekrun, who was also reportedly suspected of stealing a other. At around noon, Iowa state troopers saw Pekrun and chased him to Minnesota, where Minnesota police took up the pursuit until Pekrun re-entered Iowa. Iowa officers chased Pekrun into rural Floyd County, where he lost control of the other and crashed at about 1:15 p.m. Pekrun allegedly refused to drop a hunting-style knife when confronted by troopers Tyrel Williamson and Mark Ades, and FCSD deputy Chris Myers. Police said Myers fired a Taser, but it either missed or had no effect, and Williamson shot and killed Pekrun. In 2008, Pekrun's younger brother, Matthew Pekrun was shot and severely wounded by off-duty Milwaukee officer Theodore Puente after a foot chase.
