HENRYETTA, Oklahoma - The Oklahoma State Bureau of Investigation confirms that the sister of one of Kevin Sweat's murder victims has been found dead.

Charyl Schultz, 33, was the half sister of Ashley Taylor. Taylor was convicted murderer Kevin Sweat's fiance and one of his three victims.

The OSBI confirms that Schultz was found dead Monday at her Henryetta residence in the 700 block of East Frisco. Agents say the death is being investigated as suspicious because of the way the body was found.

Taylor was killed in 2011.
