7-year-old boy whose body was found encased in concrete in storage unit in Colorado was fed cocaine and meth

A seven-year-old boy found dead and encased in concrete in a Denver storage unit last Christmas had traces of illicit drugs in his system, a new medical report revealed.

The medical examiner in the autopsy report said that Caden McWilliams had 'cocaine metabolite and methamphetamine in liver tissue', according to CBS Denver. The medical reports further revealed that he was malnourished and had multiple physical injuries. "The postmortem examination reveals severe emaciation of the body consistent with a malnourished or deprived state," the report stated. "Numerous injuries of the head, trunk, and extremities are also noted."

The coroner was unable to ascertain the exact cause of death, stating Caden could have "experienced complications of injuries (e.g., infection or sepsis)." The boy could have also suffered "a component of asphyxia, dehydration, and/or hyperthermia."

"Given the highly suspicious nature to this death, the findings of the postmortem examination, and that the decedent is a young child who is dependent on others for his care, the manner of death is homicide," the report concluded despite the uncertainty.

The child's mother, Elisha Pankey, 43, was charged with child abuse resulting in the death of Caden and abuse of a corpse in January.

Caden's body was found encased in concrete in a locked storage unit just before Christmas but the police estimated that Caden had been dead since the beginning of May when he disappeared. The body was found after a tip from an unnamed source in neighboring Aurora, Colorado. Elisha had been charged with possession of heroin in Aurora the day before the shocking discovery.

Leland Pankey, Caden's father, is currently in jail, according to CBS Denver. He was arrested for allegedly choking his wife until she lost consciousness back in 2017. Two children were home during the alleged attack. 

In January, an order of protection was granted for his other son Camden and a legal guardian was appointed for him.
