DENVER — The mother of a 7-year-old boy who was found dead and encased in concrete inside a Denver storage unit last year pleaded guilty to a child abuse charge Thursday and will be sentenced to prison.

Elisha Pankey, 43, pleaded guilty to one count of child abuse resulting in death. She faces 16 to 32 years in prison when she’s sentenced in October.

Pankey’s son, Caden McWilliams, was found dead in a storage unit in the 5000 block of E. Evans Avenue in Denver on Dec. 23, 2018, and Pankey turned herself in to police several days later.

A report from the Denver Office of the Medical Examiner said McWilliams was malnourished at the time of his death. He had numerous injuries to his head, torso and extremities, some of which were healing, according to the autopsy. Cocaine metabolite and methamphetamine were detected in his liver tissue.

The boy’s father, Leland Pankey, was charged with murder in the case in May . In an interview with police, Elisha Pankey told investigators that Leland Pankey abused Caden while they were living in an extended-stay hotel and that he kept Caden in a dog kennel covered with blankets overnight.

Leland Pankey is set to appear in court on Sept. 13.
