Ten-year-old Jesse Wilson vanished from his Buckeye, Arizona, home in the early hours of July 18, 2016, after his adoptive mother, Crystal Wilson, reported him missing that morning. She told police Jesse, who had developmental issues and a history of wandering, likely climbed out of a second-story bedroom window during the night. Searches by law enforcement, the FBI, and volunteers turned up nothing for months.

In March 2018 a city worker found skeletal remains in a field about six miles from Jesse’s home. Forensic testing identified the remains as Jesse’s. The Maricopa County Medical Examiner could not determine a precise cause or manner of death because of decomposition; the autopsy noted several broken bones and two types of antihistamines in his system, but it was unclear whether the injuries occurred before or after death. Family members had long suspected Crystal Wilson, who later moved to Gainesville, Georgia and stopped cooperating with investigators.

What information might still help explain how Jesse ended up in that field and who was responsible?
