Nathan Hall was 18 and a high school senior when he was shot and killed in the early morning hours of April 16, 2014, in the 1400 block of North Adams Street in South Bend, Indiana. Initial reports said he was riding his bike to work; his family grew alarmed when both he and the bicycle were missing and learned of the shooting from a news report. A small memorial with teddy bears, candles, and his McDonald’s hat was placed near the scene.

Investigators say two teenagers, 18-year-old Shane Williams and Jermaine D. Munn Jr., arranged to meet Hall under the pretense of a small marijuana deal communicated through Facebook messages recovered from Hall’s phone. A witness told police the meeting was planned as a robbery. During the encounter, Munn reportedly approached Hall with a 9mm handgun and shot him in the head after Hall called out Williams’ name; Williams and Munn then took a small amount of marijuana and $80.

Williams was charged with murder and robbery and was set for trial in December 2014. Munn pleaded guilty in October 2014 to one count of felony murder as part of a plea agreement, with sentencing scheduled for December 1, 2014. Did anyone who knew Nathan or was in that neighborhood that morning see anything that could help fill gaps in the timeline?
