UPDATE: Peter Korns died Monday, Aug. 15, according to the Waukesha County Medical Examiner's office, and his body was found by police Tuesday, Aug. 16, multiple sources confirmed. A cause of death was not immediately available.


A former county sheriff's detective with a history of run-ins with law enforcement was again charged recently after allegedly violating a restraining order and resisting arrest.

Peter Korns, who served with the Waukesha County Sheriff's Department for more than 25 years until November 2014, was charged Aug. 3 in Waukesha County Circuit Court with five misdemeanor offenses: threatening injury or harm via a computer message, obstructing an officer, resisting an officer, knowingly violating a harassment restraining order and disorderly conduct.

Korns, 51, of Waukesha was previously prohibited from contacting his now ex-wife shortly after she filed a petition for an injunction against him, saying she feared for her and their two children's safety, last spring. The couple filed for divorce in February of that year, court records show.

According to a criminal complaint, Korns sent several harassing text messages to his former wife and their 16-year-old son, promising retaliation for a perceived betrayal. He also, in the text messages, appears to threaten to kill numerous people, including his ex-wife and kids and members of his ex-wife's family.

"You are going to find out that by discouraging my children from seeing me, I am going to be your worst (expletive) nightmare," Korns said in one of the messages, according to the complaint. "Have eyes in the back of your head, bi-polar (expletive)."

Korns tried to prevent officers from entering his home Aug. 3 in the 2600 block of Crest Lane when they arrived there to arrest him for sending the messages, the complaint said. He had to be restrained by multiple officers and subdued with a Taser.

This incident marks Korns' latest run-in with law enforcement. Other incidents, including one in which he reportedly threatened his former wife with a hatchet, surfaced following news reports that Korns had been suspended by the sheriff's office for violating numerous department policies.

An internal investigation revealed Korns broke 16 department rules – among them sleeping on the job, improperly using department property, associating with a felon and failing to work a full shift.

He was eventually placed on administrative leave by the department, following additional police encounters, and later negotiated a separation agreement with the department, according to a department spokesperson.

Korns left the department in November 2014 a few months before pleading guilty to an amended charge of a municipal violation for disorderly conduct – tied to the hatchet incident – and had to pay a fine $367. 50, according to online court records.

The amended charge was not part of the separation agreement, the department said.

Online court records indicate an arrest warrant was filed for Korns on Thursday, Aug. 11. No future court activity on the new case will be scheduled until he is in police custody.
