The parents of a 2-year-old boy whose body was found in their house in Jamaica have pleaded guilty to concealing his death.

Alphonso and Stephanie Warren were charged in January after neighbors stormed their Kingston home looking for the toddler because they hadn't seen him for months. Police found the mummified remains in a suitcase.

A pathology report suggested the boy likely died from disease, asphyxiation or poisoning. No one has been charged in his death. Police declined to say how the body came to be mummified.

The couple will be sentenced in upcoming weeks.

Thursday's plea comes four years after the couple abandoned a baby girl in a freezing stairwell in Toronto. They moved to Jamaica after they lost custody of that girl and their other children.
