LOCKPORT – Niagara County sheriff’s deputies investigating a case of suspected drunken driving Tuesday learned the suspect had his license revoked six times on alcohol-related charges and for refusing to submit to a chemical test.

Christopher J. Cullen, 51, of Amy Drive, was charged with driving while intoxicated, aggravated unlicensed operation, drinking alcohol in a motor vehicle and operating without insurance, registration and inspection.

A Niagara Hospice employee alerted deputies at 11:20 a.m. Tuesday when Cullen hit a pole in hospice’s Sunset Drive parking lot. Deputies said Cullen had alcohol on his breath and appeared unsteady on his feet.

A check of the vehicle found an open container of beer, according to deputies.

Cullen refused a chemical test, but was taken to Eastern Niagara Hospital in Lockport for observation after deputies said a high alcohol level reading was found on their alco-sensor.
