DUNCAN — Evidence of marijuana use was found in the search of the car allegedly involved in the thrill killing of an Australian baseball player.
Investigators found a silver grinder with green plant residue on the front passenger seat of the Ford Focus, a search inventory shows.
Investigators also recovered a spent .22-caliber casing from under the rear passenger seat.
The victim, Christopher Lane, 22, was shot once in the back Aug. 16 while jogging in Duncan, where he was visiting his girlfriend. Three teens were arrested that night after being seen near the Ford Focus.
Police have not recovered the .22-caliber revolver used in the drive-by shooting.
Chancey Allen Luna, 16, and James Francis Edwards Jr., 15, were charged with first-degree murder. Michael Dewayne Jones, 17, was charged with accessory to first-degree murder after the fact and use of a vehicle in discharge of a weapon.
The discovery of the grinder is consistent with a statement Edwards made to police that the three smoked marijuana in the car behind a Duncan motel after the shooting.
Edwards insisted in his police interview that he was not in the car at the time of the shooting. Edwards said Jones picked him up afterward to take him to the Stephens County Courthouse, where he signed probation papers on a juvenile case.
Jones has admitted driving the Ford Focus at the time of the shooting. Police identified his mother as the vehicle's owner.
The search of the car also turned up a disassembled 12-gauge shotgun in the trunk, the inventory shows. The district attorney's chief investigator, Justin Scott, reported the shotgun's serial number had been destroyed.
