Last week, a Brooklyn teen standing on a street divider in Gravesend was struck and killed by an alleged drunk driver. Driver Vitali Korzavin, 46, was arrested and charged with a DWI, speeding, and vehicular manslaughter in the death of 17-year-old Stuyvesant High School student Terence Tsao. Yesterday, Korzavin's charges were upgraded to aggravated vehicular homicide from manslaughter, after it was revealed his blood alcohol level was .32, four times over the legal limit.

Assistant District Attorney David Ingle added that a court ordered blood test taken seven hours after the accident registered .20, still two times more than the legal limit. Korzavin was ordered held in lieu of $500,000 bail; he faces up to 25 years in prison if convicted.

Terence, a senior at Stuyvesant, was standing on a Cropsey Ave. traffic island at Bay 37th St. in Gravesend when a 2000 Dodge minivan jumped the curb and hit him last Friday evening. Terence's father said his son was returning home from his school’s Board Game Society, of which he was the president: “He stayed late on Fridays to be with his friends. That was his fun night.”
