WHEAT RIDGE, Colo. (CBS4)– A doctor in Wheat Ridge has pleaded guilty to illegally prescribing pain killers.

Dr. Kevin Clemmer worked at an office building near 44th and Wadsworth in Wheat Ridge.

Clemmer over-prescribed oxycodone dozens of times. At least one case led to a deadly overdose.

Prosecutors claim Clemmer and his staff made hundreds of thousands of dollars by illegally dispensing the painkiller.

Clemmer will be sentenced in September.
