SAN ANGELO, Texas — Teenage girls, often younger than 16, were required to have sex in the soaring white temple after they were married in sect-recognized unions at a polygamist compound in West Texas, according to court documents unsealed Wednesday. The temple "contains an area where there is a bed where males over the age of 17 engage in sexual activity with female children under the age of 17," said an affidavit quoting a confidential informant who left the Fundamentalist Church of Jesus Christ of Latter Day Saints.
