Ohio state troopers locate, rescue 4-year-old girl during traffic stop

Police in Ohio rescued a missing 4-year-old Michigan girl after she was allegedly taken by her noncustodial father.

The search for a missing Oklahoma toddler has been ongoing since Tuesday, but it's still unclear exactly when she vanished.

Authorities initially reported Athena Brownfield, 4, missing on Tuesday afternoon after a postal carrier found her 5-year-old sister wandering around alone on Nebraska Avenue in Cyril around 2 p.m.

The postal carrier knew the 5-year-old girl "wasn't where she was supposed to be and notified police," at which point law enforcement realized that Athena was missing, said Oklahoma State Bureau of Investigation (OSBI) public information officer Brook Arbeitman during a Wednesday press conference posted to Facebook.

A Caddo County Sheriff’s Office deputy told FOX 25 Oklahoma City, however, that the girl may have disappeared as early as Jan. 6.

Arbeitman added that Athena has "limited verbal skills."

Cyril police immediately asked for assistance from the SBI in locating the toddler.

A Facebook post that purportedly came from the girl's family alleges that Athena and her sister were under the care of family members who left them unsupervised before Athena's disappearance.
