CLEVELAND COUNTY, Oklahoma - Sheriff's deputies in Cleveland County are looking for three people they say sexually abused a 13-year-old girl.

Felony arrest warrants have been issued for Joseph Michael Siford, 40, and Danyale Bernice Siford, 34, both of Moore; and Michelle Danae Walker, 43, of Noble.

Walker allegedly introduced the girl to the Sifords. Deputies say earlier this month, they all engaged in sex acts with the young girl. At least one encounter was videotaped. The crimes allegedly occurred multiple times in Noble, Norman and Moore.

Deputies attempted to contact Walker and the Sifords earlier this week. All three have reportedly abandoned their homes and quit their jobs. They are believed to be traveling together, but in separate vehicles, possibly headed to Michigan.

The Sifords could be driving a dark gray, 2006 Ford F-150 with Oklahoma tag 996-HYC. Walker could be driving a tan and white, 2008 Toyota FJ Cruiser with Oklahoma tag 234-HIA.

If you see them, call 911.
