New York state police say a man is dead after he fled a traffic stop and drove off a boat launch ramp into the Hudson River.
The incident started Friday night in the town of Coxsackie when a trooper tried to stop a car driven by 48-year-old Jeffrey Dean.
Police say Dean assaulted the trooper and drove away.
They say Dean headed to the Hudson and intentionally drove off a ramp into the river.
Police say Dean got out of his car and tried to swim to shore but did not succeed.
Water rescue units from several departments searched for Dean and eventually found his body.
The Greene County coroner's office is conducting an autopsy.
Coxsackie is about 30 miles south of Albany.
