TYLER, Texas —  A foster parent awarded custody of three young siblings allegedly forced into sex at swinger parties has been accused of sexually abusing a child in California in 1991.

John Orville Cantrell, 64, has been charged with sexual penetration of a person under 14 and a lewd act upon a child, Marsha Johnson of the Solano County District Attorney's Office in California said Friday.

The complaint against Cantrell was filed May 9, she said. Cantrell was taken into custody Wednesday by Wood County authorities, and Johnson said she was waiting for extradition papers to be signed.

Cantrell's wife, Margie, told the Tyler Morning-Telegraph the accusations are in retaliation for their roles in helping build the case against Mineola Swinger's Club, where authorities say children as young as 5 were taught to perform sex acts for an audience.

Margie Cantrell testified in a May trial that when she received custody of the three children, the two girls were oversexualized and the boy was angry. The children are now ages 12, 10 and 7.

"What John and I want to do is continue to seek justice for the kids in this case," Margie Cantrell said. "And if we have to climb a few mountains to get there, it will be worth it. And at the end of all this, John will absolutely be proven innocent."

Seven people have been charged with allegedly training children to perform sex acts for an audience. The two defendants tried so far have both been convicted and sentenced to life in prison.

John Cantrell said of the three siblings after the first trial, "I'm going to love them like a father."

The third trial in the swingers parties case is scheduled to get under way next week. Patrick Kelly also faces life in prison if convicted.

A court hearing in California for Cantrell has been scheduled for July 7, Johnson said.
