The blanket might suggest she’d have been done in elsewhere and dropped off there of course, too. Not sure about the reports of shots—maybe from when the body was being deposited?
Hearing shots outside of city limits in AR is not unusual and may be totally unrelated in my opinion. She lived out side of the city by the adress it was 4 miles bc in AR 1000 equals a mile usually.
Totally plausible, this was definitely not random.
