The death of a northern Iowa man who was stunned with a Taser by Worth County deputies has been ruled a homicide by the state medical examiners office. Michael Zubrod, 39, died on Sept. 22nd after he had been handcuffed by deputies following his act of domestic assault against his girlfriend, Rhonda Schukei. Zubrod had been found beating 48-year-old Schukei with a hammer and scissors. According to a news release Saturday, Zubrod had then attacked Deputy Isaac Short with a pair of needle nose pliers. Deputies Short, Shayne Hoch and John Smith had attempted to subdue Zubrod with Tasers, which seemed to have no effect upon him at the time of use, however, Zubrod became unresponsive once he was placed in handcuffs and leg shackles. Emergency officials were unable to revive him. The ruling of homicide on Zubrods death does not mean any of the deputies were at fault, just that his death was caused by another person. Zubrod had also had an artery irregularity and was under the influence of methamphetamine. Reports indicate Zubrod had been stunned 3 times with the Taser, making him the 2nd Iowa man to die after being stunned by Iowa authorities. The news release from Saturday by the Division of Criminal Investigation cites the cause of death as a heart attack following an altercation with law enforcement while under methamphetamine intoxication. Assistant director of field operations for the Division of Criminal Investigation, Gerard Meyers, indicates the state is not looking to make an arrest for the death, and the deputies have been cleared of charges. Jeffrey Greve, the Worth County Attorney, states the Iowa authorities were justified in their actions.
