Police: Mom told details of son encased in concrete

Authorities say a mother charged in the death of her 7-year-old son told a fellow inmate that the boy died in July, months before his body was discovered encased in concrete inside a Denver storage unit.

The information is contained in court records unsealed Tuesday, providing a first look at the investigation leading to 43-year-old Elisha Pankey’s January arrest. Authorities have released few details about Caden McWilliams’ death since his body was discovered in December.

Pankey has not entered a plea. She is represented by the state public defenders’ office, which bars attorneys from commenting on individual cases.

According to the records, Pankey told a woman she met in county jail that her son died inside an animal cage his parents forced him to use and they hid his body.
