Officers searched the apartment complex, but initially were unable to locate where the children live, their parents or responsible guardians. Their mother, Calean Nicol Hickey, 33, was found in the apartment complex. Police are investigating the circumstances.

“I don’t’ know the details and the officers are sorting through the details that they gathered from their mother,” Matt Barnes with Thornton police said. “But obviously they felt that it rose to the level where she could be arrested for investigation of child abuse.”
