Authorities said that her last known possible direction of travel was south on Highway 7, south of Hot Springs in a White 4-door 2014-2017 Honda Accord.

Case was leaving work with a friend when an unknown White woman stated she was lost and that her parents were living in a Condo in Hot Springs, KNWA-TV reported, citing police. 

The woman reportedly asked Case if she could use the teen’s phone before changing her mind, asking Case to come closer to her car so she could use the GPS coordinates.

Case’s friend had left to bring their car around during this time. When the friend returned Case was gone and the missing teen wouldn’t answer her phone, KHBS-TV reported.

The friend called Case’s mom, who tried calling her daughter’s phone multiple times. Investigators said Case eventually answered, saying "everything is fine," before a male voice demanded $10,000 for Case’s return or he would kill her and cut her up, the reports said.

The call ended following the male’s statement and no contact has been made since.

Authorities asked anyone with information on Case or the vehicle to call the Hot Springs Police Department at 501-651-7711.
