Authorities in Oklahoma are asking for the public’s help in locating two teen sisters who were reported missing on October 17.

The Edmond Sun reported that Shakira Russell, 13, and Tiara Russell, 15, (pictured left and right) left their Edmond home through a bedroom window. The sisters left behind medications that they need to take, according to KTUL.

The girls’ adoptive parent initially told police that the pair were attempting to meet their biological parents, one of whom lives in Oklahoma City. Since then, she’s told The Sun that she’s been speaking to the biological parents on a daily basis and that they have yet to hear from the girls.
