News 4 Investigates Daily Briefing on this story

(KMOV) - An area police officer is on unpaid leave after making a series of verbal threats to a driver.

The incident happened around 2 a.m. Saturday in a commuter parking lot near I-55 and Revis Barracks in St. George.

It started when Brett Darrow pulled in the lot to meet with friends.   Sgt. James Kuehnlein followed him and quickly got upset when the driver asked why he was being pulled over.

That driver caught the officer on tape cursing and even threatening to make up charges against him.

As driver Brett Darrow questions Sgt. James Kuehnlein, the officer's temper quickly flares.

Darrow says he runs his in-car camera anytime he's driving to protect himself against scenes like that. 

Darrow says he mounted the camera after getting a ticket a year-and-a-half ago he doesn't think he deserved. 

The St. George police chief says this is the first time he's ever received a complaint against Sgt. Kuehnlein during his 2 years with the department.

The chief is investigating and will watch the dash cam video from the officer before making any decisions. 

Darrow says he wants Sgt. Kuehnlein fired.  Right now the Sgt. is on unpaid administrative leave. 

The police chief says by the end of the week we should know Sgt. Kuehnlein’s fate.  

This isn't the first time Darrow has posted video like this. Back in December he had a run-in during at a DUI checkpoint.

Darrow says he just wants to make sure the people hired to protect and serve don't become a danger to citizens.
