Search and rescue efforts are being scheduled this weekend to help find a missing Caddo County mother. Dawn Sherrill, 55, went missing on July 21. She was last seen near State Highway 8 and County Road 1376, south of Anadarko. Law enforcement issued a Silver Alert for Sherrill the next day. “I’m beyond myself,” said Dylan Sherrill, Dawn’s son. “I’m almost to where I can’t feel anything, I can’t think, I can’t process.” Sherrill’s family met with members of the Oklahoma City Metro Search and Rescue Team Wednesday evening to solidify search and rescue operations. Anyone wishing to volunteer their time to help find Sherrill is being asked to meet at the First Baptist Church in Anadarko at 9 a.m. Saturday.
