Today is the one year anniversary of a Nocona teen’s sudden disappearance.

18-year-old Caleb Diehl was reported missing last March, after officials say he borrowed a truck from a family friend named Ricky Dale Howard.

The truck reappeared at Howard’s house a few days later, but Diehl is still missing.

Tonight his friends and family are hosting a candlelight prayer service starting at 7:30 p.m. in the Nocona Downtown Park.
