Medical Examiner rules Tulsa children accidentally drowned

The Oklahoma medical examiner's office has ruled that two Tulsa children whose bodies were found in waterways in May accidentally drowned.

Autopsy reports released today [Friday] say both 3-year-old Miracle Crook and her 21-month-old brother, Tony Crook, drowned after being last seen on video holding hands and walking through an opening in a chain-link fence toward a rain-swollen creek that flows into the Arkansas River.

Their mother Donisha Willis has pleaded not guilty to second-degree murder charges in the deaths.
