Tony Vince Lewis Jr., a 32-year-old African American man, was shot and killed on March 17, 2015, at a gas station in Jacksonville, North Carolina. The shooting was a drive-by: a moped rider wearing a full-face helmet approached Lewis’s car and fired shots. Authorities said the two men knew each other, but the motive has not been disclosed.

Investigators identified the moped rider as Travares T Francis Waters, and the Onslow County Sheriff’s Office issued a murder warrant. A nationwide search followed and Waters was later arrested in Texas. The case underscores the difficulty of closing gaps about motive and circumstance even after an arrest has been made.

If anyone knew Tony’s movements that night or saw a moped near the gas station on March 17, 2015, please share what you know.
