Search underway for 2 women in Oklahoma after "suspicious disappearance"

Authorities are investigating the disappearance of two women in western Oklahoma, who were last seen together in a vehicle later found abandoned in a rural area near the highway. Law enforcement said 27-year-old Veronica Butler and 39-year-old Jilian Kelley went missing under "suspicious" circumstances.

The Oklahoma State Bureau of Investigation on Sunday announced its involvement in the probe at the request of the Texas County Sheriff's Department, whose jurisdiction includes the isolated part of the Oklahoma panhandle where the women's car was discovered. 

Oklahoma Highway Patrol issued an Endangered Missing Advisory for Butler and Kelley, on behalf of the sheriff's department, on Saturday. That alert deemed both women "at-risk," although few details have been shared publicly about the events leading up to their disappearance.
