On April 7, 2019, gunfire erupted at the Naptown Riders motorcycle clubhouse near 25th Street and Sherman Drive in Indianapolis, killing 76-year-old John Richard Boxley. Known to friends and fellow riders as Killer, Boxley was among five people struck during the early-morning shooting; he and 42-year-old Yolanda Bailey later died of their wounds. Witnesses described a chaotic scene as attendees scrambled for cover while others were wounded.

Indianapolis Metropolitan Police launched a homicide investigation and detained large numbers of witnesses for questioning as detectives worked to reconstruct the sequence of events. Initial reports did not name suspects or announce arrests, and investigators faced conflicting accounts from the crowded clubhouse. Why did the shooting occur and who was responsible for bringing deadly gunfire into that gathering?
