In the summer of 2017 Mount Vernon, New York, lost a young man to a violent, targeted attack. On August 11, 31-year-old Brandon J. Peterson was found with multiple gunshot wounds; emergency responders treated him, but his injuries proved fatal. Investigators described the shooting as not random but premeditated.

The Mount Vernon Police Department opened an immediate homicide investigation, questioning several people as detectives worked to reconstruct Peterson’s final hours and explore possible motives tied to his personal life or activities. No arrest was announced in the initial aftermath, and the case remained open for years while detectives periodically revisited leads.

The killing left a family and community seeking answers. If anyone has information about Brandon Peterson, the scene on August 11, 2017, or contacts who might help this long-open investigation, please come forward.
