INDEPENDENCE, Mo. (AP) — The father of two Kansas City-area children whose remains were found in a shallow grave more than three years after they disappeared confessed publicly and was charged Tuesday in their shootings.

Dan Porter, 44 — who already is serving a 38-year prison term for kidnapping his son, Sam, 7, and daughter, Lindsey, 8, to terrorize their mother — was charged with two counts of first-degree murder.

The children's bones were found in September in a wooded area near the Missouri River in nearby Sugar Creek and were identified using dental records.
