Tyler Christopher Payne was a five-year-old listed as last seen on January 15, 2007, in Tucson, Arizona, but court findings place the events that led to his disappearance during 2006 when he was four. Tyler and his younger sister Ariana had been living with their father, Christopher Mathew Payne, and his girlfriend, Reina Gonzales, while legal custody belonged to their mother, Jamie Hallam. Evidence presented at trial described the children as confined in a bedroom closet, deprived of basic care, cleanliness, fresh air, and adequate food; by summer 2006 their confinement had become effectively permanent and they were severely malnourished.

Investigators recovered Ariana’s badly decomposed remains after a storage unit containing the children’s bodies was abandoned and its contents discarded; Tyler was not found with her. Police searched a municipal landfill and other areas but never recovered Tyler’s remains, and authorities believe his body may have been unknowingly carried away with ordinary refuse. Gonzales pleaded guilty to two counts of second-degree murder and later testified against Payne. A jury convicted Christopher Payne of two counts of first-degree murder, child abuse, and related charges, and sentenced him to death.

Does anyone have information about Tyler’s last known movements inside the Tucson home or the storage unit that could help explain where his remains went?
