HAMDEN Town resident Semaj Reddick-Streater, a senior at ACES Whitney North High School, could not wait to attend his upcoming graduation with his baby girl, his family said. “All he could talk about was walking across that stage with his daughter,” said Reddick-Streater’s mother, Malika Reddick. But on Sunday night, just a couple of weeks before the big day, the 18-year-old was shot in the 200 block of Circular Avenue. He was pronounced dead.
