David Anthony Vaughn, 40, was shot to death after an argument in rural Wimer, Oregon, on Sunday, April 23, 2017. The Jackson County Sheriff’s Office found Vaughn with a fatal gunshot wound at a residence in Rogue River after what police described as an irrelevant argument that escalated from a verbal dispute with an acquaintance.

Investigators identified and arrested Michael Wayne Carnahan in connection with the shooting. Carnahan was charged with murder as the case moved into the judicial phase; investigators examined motive and the sequence of events that led to the fatal encounter.

Are there details about Vaughn’s activities that day or witnesses in Wimer or Rogue River who can help fill gaps in the timeline?
