“This is a very active and ongoing investigation and right now our top priority is her whereabouts. And then finding out who is responsible. We need to find this little girl,” Arbaitman said. “She is in the elements on her own. So, is it endangered? Yes. But was she a victim of physical harm? This is yet to be determined.”

This ground search continued throughout Wednesday but ended after volunteers searched “the entire city,” Arbaitman said.

“Today at 16:00 Oklahoma Highway Patrol (OHP) The Emergency Response Team (ERT) has completed a web search with local volunteers. These volunteers were released after a search of the entire city, every known vacant home and local waterways,” OSBI said in a separate statement Wednesday afternoon.

It is unclear how long she was missing before her disappearance became known.

“We are still working on coming up with precise timelines,” Arbaitman said.

Details about the house where the girls are staying are also not immediately clear, and the whereabouts of the girls’ parents or guardians at the time of Athena’s disappearance is unknown.

“This is part of an ongoing investigation,” Arbeitman said Wednesday morning when asked about who was supposed to be watching the girls, according to KOCO News.

Many details about the 4-year-old, who was originally told by authorities to be 3 but have since been corrected, are not known. Subsequently, an Amber Alert was not issued because her disappearance did not comply with specific regulations, Foster said.

“There are specific recommendations and things that we need to follow,” he explained. “Not every part of this guide played a role in this. So the next best thing we could do was post a missing and missing notice that went out within a 15 mile radius of where she went missing.”

Law enforcement officials continue to conduct interrogations and review surveillance footage in the area. They are also asking anyone with doorbell cameras or footage of the area near West Nebraska’s 200 block to donate their resources to help with this effort.
