The lawyer for polygamist sect leader Warren Jeffs says he will depose a former member of the sect about her links to the raid on their Texas compound.

Flora Jessop is scheduled to give her deposition Monday and be asked about telephone conversations she may have had with Rozita Swinton, a Colorado woman who played a key role in launching the investigation into the Fundamental Church of Jesus Christ of Latter Day Saints.

Jeffs, the leader of the sect, faces multiple charges involving members who allegedly had sex with underage girls.

The Salt Lake Tribune says it was Swinton, 33, who made the original phone call to a domestic violence shelter while claiming to be a 16-year-old resident of the compound.

Attorney Michael Piccarreta wants Jessop to produce any recording she made of her conversations with Swinton and with police and child welfare officials.

The investigation led to the dramatic police raid on the rural ranch in which more than 400 children were placed in protective custody.
