I can't imagine the pain that family must be feeling. I'd like to not only offer my condolences, but pray for them as well.
Heavenly Father,
Please bless the mother and father who have lost their child. Heal their hearts and comfort them in the ways that only You know how. God, give them peace, who's child You've called away, and the joy in knowing they will reunite someday. In Your name I pray. Amen.
