Katherine's older sister, singer Holly Audrey Williams, commented on the crash Sunday morning in an Instagram post. "I have no words," wrote Holly, alongside a photo of her father and sister with other family members. "On Friday morning I talked the family into taking this picture and had no idea it would be our last together with my precious little sister Katie."
She explained the family went to her great aunt's funeral on Thursday, and now, "are faced with another one."
"ALL we need is prayers. My daddy. My little brother. Katie's husband," she continued. "My niece and nephew. Her Mama. The Dunning family. All of us. So. Many. Prayers. Jesus is close. Thank you all."
