Craig Wingard, 33, was killed after an argument over a set of car keys outside an apartment complex in East Woodrow, Tulsa, on July 5, 2015. A former U.S. Marine who enjoyed hunting, fishing and BMX biking, Wingard was shot multiple times through the driver’s side window of a vehicle after going to the residence to retrieve a stolen item. He was taken to a hospital and died three days later on July 8, 2015.

Police identified 17-year-old William Dean Campbell and his girlfriend, Sarah Helton, as the suspects. Campbell was accused of firing a .22-caliber rifle and was sought on a first-degree murder charge while Helton was charged as an accessory. Campbell later admitted to firing the weapon, saying he intended only to intimidate. He was tried as an adult, convicted by a jury of first-degree murder and a weapons charge, and given a life sentence plus five years; the Oklahoma Court of Criminal Appeals upheld the sentence.
