Seventeen-year-old Alvin Sanders, known to some as A.J., was shot and killed on the evening of Saturday, October 7, 2017, in University City, St. Louis, Missouri. He was at a gathering in the 7000 block of St. Charles Rock Road when an argument escalated and a single, fatal gunshot struck him. University City police found Sanders at the scene after a call just before 10 p.m.; he died despite responders’ efforts.

Investigators quickly identified another 17-year-old, Jeremiah D. Lewis of St. Ann, as the primary suspect. Lewis was taken into custody and the St. Louis County Prosecuting Attorney’s Office moved to charge him as an adult with second-degree murder and armed criminal action. A warrant was issued and bail was set at $250,000, cash-only.

Alvin’s death ended a young life in a moment of conflict; details about what sparked the argument remain unclear. Did anyone at the gathering or nearby that night see what happened or have information about the altercation?
