The Bossier and Caddo Parish Sheriff's Offices need the public's help regarding numerous packets that have been delivered to various churches in both parishes. They stress that there's no physical danger associated with the packets, but they do contain CDs with pornographic images on them. So far, at least two churches in Bossier Parish -- and seven in Caddo -- have received the packets. The discs, along with a typed narrative of the writer's personal beliefs, were mailed to the churches in large manila envelopes with a typed address label on the front and a label on the back. They have no return addresses. Anyone who receives such an envelope should not open it, but instead contact the proper sheriff's department.
