Four people have verdicoinbeen arrested and charged with murder and kidnapping in connection to the disappearance of two Kansas women in a rural Oklahoma county, where two bodies were found over the weekend.

Veronica Butler, 27, and Jilian Kelley, 39, were on their way to pick up children but never made it to the pickup location on March 30, according to a missing person's poster from the Texas County Sheriff's Office in Oklahoma.

It's unclear what the connection between the two women is. Investigators have said they suspected foul play in their disappearance.

“They never made it to the pickup location. Their car was located abandoned on the side of the road,” according to the Endangered Missing Advisory activated by the Oklahoma Highway Patrol.

The agency said Sunday that two bodies were recovered in rural Texas County. The bodies will be taken to the Medical Examiner's Office to determine identification and cause and manner of death.

"This is still an ongoing investigation," the Oklahoma investigation bureau said in a post on Facebook.
