Rochester, MN (KROC AM News) - A longtime local DNR conservation officer helped Olmsted County deputies arrest two robbery suspects Friday.

The Sheriff’s Department says Lt. Dean Olson was driving near Dover around 11:30 a.m. when he spotted a car driving erratically down the road. Olson stopped the vehicle and was told the car was overheating and the driver was swerving in an effort to cool the engine. Olson told the driver to be careful and drove off.

Moments later, Olson heard a dispatch report about a liquor store robbery in nearby Eyota and noted the suspect’s vehicle matched that of the car he had just stopped. Olson turned around and spotted the car parked along the road and saw its two occupants had been offered a ride by a passing truckdriver. Olson detained the two until deputies arrived and took them into custody.

A department spokesman says 28 year old David Martinez later admitted he was the one who held up the liquor store at gunpoint. A 36 year old Rochester woman who was with him was also arrested but she may not be charged as she told investigators she had no idea Martinez had robbed the business.
