A Riverhead teacher who is an assistant chief of the Jamesport Fire Department has been charged with driving drunk and crashing his department-issued vehicle into several street signs Saturday evening, Southold Town police said.

David J. McKillop, 55, of Aquebogue, was charged with driving while intoxicated and leaving the scene with property damage, police said.

McKillop, the department’s first assistant chief, was driving about 6:30 p.m. when he crashed the chief’s vehicle into “multiple” street signs at Rt. 25 and Tuckers Lane in Southold, police said. Witnesses said McKillop was driving west on Rt. 25 when the car left the road, police said.

Jamesport Fire Chief John Andrejack said Sunday that McKillop was a long-serving department volunteer. “He has been a member for almost 20 years with a spotless record. We’re still gathering information right now,” Andrejack said Sunday in a prepared statement. He did not want to comment further.

The police report indicates that McKillop’s employer is the Riverhead School District and that he is a teacher.

There was damage to the car’s front end and a large hole in the windshield, police said.
