A man, who was stopped by police after a short chase Saturday afternoon on I-86, has been charged with DWI while ability impaired by drugs. Police say that 30 year-old Cory Pearse led the troopers on to South Branch Road, when he then fled his vehicle on foot, crossed the eastbound lanes of Interstate 86, and stopped running once he was in the median. Pearse reportedly admitted to using drugs and marijuana prior to driving, was arraigned in Friendship Town Court and sent to the Allegany County Jail.
