ST. PETERS, Mo. (KMOV.com) – A woman was sentenced Tuesday for using a rifle to rob a St. Peters gas station and leading police on high-speed chase in August, 2012.
Circuit Judge Daniel Pelikan sentenced Helen Denson, 43, to 15 years in prison.
In a deal with prosecutors, Denson pleaded guilty to second-degree robbery, armed criminal action and resisting arrest.
Denson walked into the BP gas station in the 150 block of Salt Lick Road around 2:35 a.m. on Aug. 14, 2012 and displayed a rifle to the clerk on duty.
Police said Denson then demanded money and lottery tickets.
Denson was handed an unknown amount of cash and about $200 worth of scratch-off lottery tickets and left the store. She fled the scene in a four-door black 2000 Chrysler 300 in an unknown direction.
Officers later spotted a vehicle matching the description traveling on eastbound Highway 70.
When they attempted to stop the vehicle, the suspect sped away. St. Peters and St. Charles officers gave chase and said Denson reached speeds in excess of 100 mph at one point.
Denson was arrested after her vehicle struck a curb on North 2nd Street near Olive Street. Everything taken from the station was recovered from the Denson’s vehicle.
