Three cops in Montana have been suspended without pay for having sex with a former civilian police department employee, including some on-duty romps in the basement of City Hall, authorities said.

Billings Police Chief Rich St. John on Wednesday declined to name the three veteran male officers, but identified the woman they had sex with as Rawlyn Strizich, who was fired in February after admitting she stole prescription painkillers from the department’s evidence room, Last Best News reports.

“We’re talking really good officers who made a bad decision — a really, really bad decision,” St. John told the online news site.

Two of the officers were docked two weeks’ pay for having sex with Strizich in the department’s record storage room in the basement of City Hall. The third cop was suspended without pay for one week after having sex while off duty with Strizich inside a city-owned police patrol car — “or close to it,” St. John said.

The officers have admitted to the encounters, which occurred from mid-2016 through early 2017, the Billings Gazette reports. St. John downplayed the trysts during an interview with the newspaper, saying they had nothing to do with the earlier theft at the evidence facility.

“We’re basically talking about no criminal offenses,” St. John told the newspaper. “We’re talking about policy violations that fall into moral turpitude. What I disciplined them for is basically rules of conduct, that officers and the general public would not think that this behavior and location specifically would be appropriate.”

St. John said he had to schedule the suspensions due to staff shortages and noted the potential loss of investment in the officers had they been fired. All of the officers are “remorseful” for their conduct, he said.

“I look at their work that they have done, whether they’re salvageable, the time that’s elapsed with this thing,” St. John told the Billings Gazette. “We have a lot of money invested in these people, and if they’re salvageable, we want to do that. I also want them to learn that this isn’t acceptable behavior and send a message to the rest of the department that this is unacceptable.”
