In the early morning hours of October 4, 2015, a dispute that began in an after-hours club in Staten Island spilled into the street and ended with two brothers fatally shot outside a gas station at Targee Street and Vanderbilt Avenue in Clifton. Terrell Ford, 27, had followed the altercation from the club trying to act as a peacemaker. His older brother Justin Ford, 28, arrived after finishing a shift at a local car service to help him.

A gunman opened fire; Terrell was struck in the torso and Justin was hit in the back. Both were taken to hospitals and pronounced dead. Four days later, police arrested 30-year-old Wayne Thomas and charged him with murder and criminal possession of a weapon. Thomas was on parole for a prior manslaughter conviction at the time of the arrest.

What details about that night or the neighborhood might help explain how the dispute escalated so quickly?
