PITTSBURGH — Dozens of people gathered Monday at the basketball court at the East Hills Community Center to honor 18-year-old Tristan Taylor, who was killed in a shooting on June 30. His mother, Jokima Brown, said she is focused on keeping her son’s memory alive while continuing to seek justice. “I just miss talking to him, I miss hearing his voice and if I had known I wasn’t going to get to see him again, I would’ve hugged him so tight that day,” Brown said.
