Kuwan Collins, 40, was shot and killed in the early morning hours of July 6, 2014, in the Concord neighborhood of Staten Island.

The killing was part of a violent two-day spree by Tyrell Brown that included an earlier murder that day, a carjacking of a 29-year-old man’s black Hummer, a high-speed incident at the Verrazano-Narrows Bridge, and additional armed robberies while Brown was on the run. Law enforcement arrested Brown on July 8, 2014, and he was later charged in the killings.

Does anyone have information about Collins, where he lived, or the Britton Avenue area around July 6, 2014 that could help fill in what happened?
