The Lewisville Noon Rotary, of which both Bobbie Mitchell and Fred Mitchell are members, said on Facebook that Bobbie was listed in stable condition and transferred to the ICU to recover from her stab wounds.

In a Facebook post, Denton County Judge Andy Eads called the incident a “huge tragedy.”

“I ask that you keep her and her family in your prayers as she recovers,” Eads wrote. “Her beloved husband, Fred Mitchell, a longtime friend, will be greatly missed. Please honor their privacy as the family navigates this horrible tragedy.”
