A Buffalo man is charged with aggravated driving while intoxicated and a host of other charges following a motor vehicle accident that injured an 11-year-old child late Friday night near the city’s Delavan-Grider neighborhood, city police reported.

John C. Coston, 37, of Walden Avenue, who does not have a valid driver’s license, later registered a blood alcohol level of nearly three times the legal limit, according to Northeast district officers.

Police say Coston was driving recklessly northbound on Cornwall Avenue near Northland Avenue just before 10 p.m. Friday when he hit another vehicle as it was attempting to make a left turn, injuring a child who was sitting in the front seat of that vehicle.

Coston refused a field sobriety test but later submitted to a chemical test that registered a 0.22 percent blood alcohol level. An open container of Remy Martin cognac was found inside his vehicle, and Coston admitted to having two shots of cognac, according to the arrest report.

Officers also say a baggy of marijuana was found in Coston’s shirt pocket while he was being processed at Central Booking.

In addition to aggravated DWI, Coston is charged with DWI, unlicensed operation of a motor vehicle, drinking alcohol in a motor vehicle on a highway, endangering the welfare of a child and unlawful possession of marijuana.
