OKLAHOMA CITY — 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.

Martin declined to comment on the charges against Morris, but said he anticipated entering a not guilty plea on Morris’ behalf.

Court records show an Osage County judge set a $50,000 bond and ordered Morris to surrender his passport to the local sheriff.

Morris resigned last year as pastor of Gateway Church in the Dallas suburb of Southlake after a woman accused him of sexually abusing her in the 1980s.

The alleged abuse started in 1982 when the victim, referred to in the indictment as C.C., was 12 years old and Morris was a traveling evangelist staying in Hominy, Oklahoma, with her family, according to the attorney general’s office. The abuse allegedly continued for four years.
