Police investigators are looking into whether a Yale graduate student shot to death over the weekend was a targeted victim in a road rage incident that possibly occurred after a car accident. New Haven Police Chief Otoniel Reyes said Monday that police believe the shooting of Kevin Jiang was not a random act and it was possible he was targeted. The 26-year-old Seattle native and Army veteran was shot multiple times on a New Haven street Saturday evening. No arrests have been announced. Jiang was attending Yale’s School of the Environment and had just gotten engaged to be married.
