A former pastor of a Texas megachurch is expected to turn himself into Oklahoma authorities Monday on child sexual abuse charges. Robert Preston Morris, 63, is expected to surrender to officials in Osage County, where he was charged last week with five counts of lewd or indecent acts with a child, his attorney, Mack Martin, told The Associated Press. Court records show an Osage County judge set a $50,000 bond and ordered Morris to surrender his passport to the local sheriff.
