Ponchatoula, La. Authorities began digging today behind a church suspected of being the home of an alleged cult that had sex with children and animals.
Crime scene experts from the F-B-I, along with police and sheriff's officers, conducted the dig with a backhoe.
Nine people have been arrested in connection with the investigation, but authorities say a dozen or more additional people could be involved.
In the latest arrest, F-B-I agents and East Baton Rouge Parish sheriff's deputies took Patricia "Trish" Pierson into custody when she arrived at the Baton Rouge Municipal Airport on a flight from Tulsa.
Pierson was arrested as a fugitive and then transferred to Tangipahoa Parish, where she was booked on charges of sexual battery and principal to aggravated rape.
Another woman, Nicole Bernard, wanted on a charge of aggravated rape, has waived extradition in Ohio, and will likely return to Louisiana within 10 days.
Her ex-husband, Austin Aaron Bernard, was arrested May 17th on a charge accusing him of making a girl under the age of 13 perform a sex act -- a potential capital offense.
Seven of the eight people arrested, including Pierson's husband, Allen R- Pierson, remain in jail without bail, Covington said.
Lois Ann Mowbray was released on bond. She was arrested on counts of obstruction of justice and failure to report a felony.
The nine people arrested are believed to be the central figures in the alleged cult.
