Police have arrested one of the two "persons of interest" in the shooting death of a Firth man after an argument in an Idaho Falls motel parking lot. Police say 22-year-old Jayson Burns was arrested Tuesday afternoon on suspicion of two counts of aggravated assault in the death of 24-year-old Anthony Camp. Investigators say Camp and at least two others were arguing in the parking lot of the Super 8 motel shortly before 3 a.m. Tuesday. Sgt. Phil Grimes says one of the people pulled a gun and Camp and a woman got into a car and drove away. Camp was shot in the back as he drove and the car ended up crashing into a house. Police say 23-year-old Geoffrey Elawadly is the other person of interest.
