Families of Caylee and Haleigh gather

Sunday night marked the nationwide "Vigil of Hope" for missing children. In Lake Mary, two grieving families attended a vigil in a show of support from one mother to another.

The bond Cindy Anthony and Crystal Sheffield share is a pain deep inside that only those who have a missing child can feel.

"It brought back more emotion than I anticipated, but that emotion's all right because that's how we help other people," Cindy Anthony said.

While George and Cindy Anthony still mourn the death of their granddaughter Caylee Marie, they spoke at the vigil to make people aware of missing children nationwide. "Coping with someone missing is the most gut wrenching, sick open wound feeling that you could ever have."

Haleigh Cummings grandmother, Marie Griffith agrees. "I can't explain to you the hurt right here. It's right here aching constantly."

Marie's daughter, Crystal, is devastated. It has been nearly three months since her daughter Haleigh was reported missing. "Whoever has her, I know you're watching. Please bring her home. Haleigh I love you. I won't ever give up on you." Seconds later, Crystal started to collapse.

Cindy knew exactly what to do. "I've been there. People have put chairs underneath me many times."

Marie said it hasn't been easy. "She falls apart. She can't take the stress. It's awful."

That's why Haleigh's family is glad to have help from Caylee's family. "It means a lot. It means a lot. I didn't know anyone was going to be here other than us."

Marie added that she has been frustrated with the dying media coverage. She also wished investigators would do more to find Haleigh.
