TULSA, Okla. (AP) — A body found in an east Tulsa creek is believed to be that of a second missing toddler who disappeared with his sister last week, according to police.

“We do know it’s a young, young male,” and the body was sent to the medical examiner for identification, Tulsa police Lt. Richard Meulenberg said.

Searchers found the body about 5 p.m. Wednesday, less than a day after the body of a young girl was found in the Arkansas River.

Police have been searching since Friday for 2-year-old Tony Crook and his 3-year-old sister, Miracle Crook.

“At this point, all the signs are pointing to these are the two children that we’ve been looking for,” Meulenberg said.

Police have said the two were last seen on security video outside their east Tulsa apartment holding hands and walking toward a creek whose waters eventually flow into the Arkansas River.

The mother of the children, Donisha Willis, 24, is jailed on charges of child neglect and assaulting a police officer.

The girl’s body was found in the Arkansas River, about 40 miles from the apartment, but about 100 miles away by waterway, said Terry Sivadon, a member of the task force that recovered the boy’s body, about 15 miles away by water.

Tulsa police have said the area received heavy rainfall during the weekend and the creeks and rivers were flowing rapidly.
