WAUKESHA COUNTY — A Waukesha County detective considered “a hazard on the job” is in trouble for domestic-related disorderly conduct.

Co-workers say that Waukesha County Detective Pete Korns is a waiting car wreck.

Having been officially reprimanded nine times since 2011 for misconduct and being suspended for three days earlier this year, the detective has been able to remain the job.

FOX6 News recently found out that  Korns was placed on administrative leave, after co-workers suspected he had been coming to work high on opiates.

The Waukesha County Sheriff’s Department confirms there’s an ongoing investigation.

This week, Waukesha police arrested Korns for domestic-related disorderly conduct.

That’s when the sheriff finally suspended Korns’ arrest powers.

Korns’ co-workers have caught him sleeping on the job and snoring, using his work computer for personal things — like accessing Craigslist more than 6,000 times, and researching steroids.

In January, he’s accused of driving his squad car for two months without a valid driver’s license.

He has also been in trouble for not properly storing evidence.

“I’ve been here 35 years so I’ve known this employee Pete Korns from the day he started. I’ve supervised him personally for many, many years and I’ve realized overall he is a good employee,” Trawicki said.

In June, Trawicki told FOX6 News he felt like Korns’ behavior had changed for the better.

“If I thought this was a person who deserved to be terminated, then I would make that recommendation. I’ve done it before,” Trawicki said.

The Waukesha County Sheriff’s Department came under fire this summer after a FOX6 investigation revealed the laundry list of violations that have been leveled against Korns over the years.

The Waukesha County Sheriff’s Department has issued this statement to FOX6 News:

“On September 9, 2014, Waukesha County Sheriff’s Department Detective Pete Korns was arrested by the City of Waukesha Police Department on an allegation of Domestic related Disorderly Conduct.

Detective Korns has been with the Waukesha County Sheriff’s Department for approximately 26 years and is assigned to the Detective Bureau.

Consistent with our normal practice, Detective Korns has been placed on administrative leave and his arrest powers have been suspended pending the outcome of the City of Waukesha Police Department’s investigation and our internal investigation.  We will not be releasing any further details of the case until the conclusion of both investigations.”
