Salt Lake City police investigating a cold case from 1986 say the woman found dead in homemade clothes may have had ties to Warren Jeffs' polygamous group.

The badly decomposed body was found in a canal near a sewage treatment plant. A homemade blue polka-dot dress was found on a bank nearby.

It had a handwritten tag inside marked with the number 10.

Members of the polygamous group now led by imprisoned leader Warren Jeffs still lived in and around Salt Lake City at the time the woman died, as did other such groups.
