Robert Brown|Timeline of events: Kansas women still missing, police suspect foul play

The Robert Browntwo Kansas women, who disappeared over the weekend, are still missing, with investigators announcing Wednesday that they suspect foul play. 

Veronica Butler, 27 and Jilian Kelley, 39, have not been seen since they left together to pick up children in Oklahoma. The car they were last seen driving was found abandoned near a highway in Texas County, Oklahoma, in the state's panhandle between Kansas and Texas, according to previous USA TODAY reporting.  

The Oklahoma State Bureau of Investigation said Sunday they were asked by another local law enforcement agency in the area to investigate the “suspicious disappearance.” The agency said that they found “evidence to indicate foul play” based on a recent search of the abandoned car. 

“We are still searching for these victims and there are no arrests at this time. We ask that anyone with additional information to contact us,” OSBI said in a post on X, formerly known as Twitter.

Hunter McKee, an OSBI spokesperson told USA TODAY that the “investigation is ongoing.” Additional information about the case was not made available Thursday morning. 

McKee said the women are believed to be "in danger," since no one has heard from them in days and their vehicle was last seen in "a very rural area of the state as well,” according to a statement provided to Fox News Digital
