On September 9, 1975, Peltier purchased a station wagon.[1] The following day, AIM member Robideau,[31] Norman Charles and Michael Anderson were injured in the accidental explosion of ammunition from Peltier's station wagon on the Kansas Turnpike close to Wichita.[28] Agent Coler's .308 rifle and an AR-15 rifle were found in the burned vehicle.[28] The FBI forwarded a description of a recreational vehicle (RV) and the Plymouth station wagon recently purchased by Peltier to law enforcement during the hunt for the suspects.[28] The RV was stopped by an Oregon State Trooper, but the driver, later discovered to be Peltier, fled on foot following a small shootout.[28] Peltier's thumbprint and Agent Coler's handgun were discovered under the RV's front seat.[28]
