I just transcribed from video, the prayer that RC read at the Candlelight vigil on May 18, 2012. There was only one part that I couldn't understand one or two words, and there I'll put a **.
"Father, I am totally helpless in this situation. Father, only You can save my daughter. Only You know where she is located at.(sic) Only You, Father, know who this evil, mad predator is and how we can find him. Help the detectives to find...to find my daughter. (Pauses for 5-10 seconds while she composes herself) Father, please, in the name of Jesus Christ, move now to save my daughter's life from this unholy and foul creature. Give her a second chance to live again. Do not let her go home to be with You before it is her time to actually do so. Both myself, my husband, my boys and all of our family members and friends are now standing here before You and asking that you take this assignment of ** to bring my daughter back home quickly, as quickly as you deem possible. My daughter's life is now in Your mighty hands. Let Your Perfect Will now be done on this situation. We ask that You please have mercy on both our daughter and our family and bring her safely back home so we can all be reunited with her. Thank You, Father. Thank You, Jesus, for hearing all of our cries and petitions on this extreme matter. In Jesus' name. Amen."
Before she read it, she indicated that this is the prayer that she and Isa's family have said every night, together, since her disappearance.
