We've got Rob Lowe playing Drew Peterson, Kaley Cuoco cast as his missing fourth wife, Stacy Peterson, and now Hollywood has named two more actors to play some of Bolingbrook's more notable residents in the Lifetime drama based on the true crime sensation Fatal Vows: The Tragic Wives of Sergeant Drew Peterson.

According to the website tvline.com, actress Catherine Dent will play "Sheryl," a character based on  Stacy's next-door neighbor, Sharon Bychowski.

Also, the website for Variety has reported that actor William Mapother will play Peterson's stepbrother, Thomas Morphey.

Dent has appeared in the television series Law & Order: LA and The Closer, and the TV movies Natalee Holloway and The Bad Son.

Mapother, whom tvline.com says is a cousin of actor Tom Cruise, has appeared in Law & Order: Criminal Intent, Lost, and The Young and the Restless.

In reality, Bychowski played a key role in keeping her dear friend's case in the public eye as she strove to get justice for the missing Stacy.

Morphey, whose father married Peterson's mother after each of their respective spouses died, testified under oath that he helped Peterson carry a blue barrel that he believes contained Stacy's dead body out of the Peterson home.

The television adaption of Fatal Vows has reportedly been titled, Untouchable: The Drew Peterson Story.

While the state police consider Stacy Peterson's October 2007 disappearance a "potential homicide" and have named Drew Peterson as the sole suspect in the investigation, they have yet to charge him with harming her.

The state police have charged Peterson with the murder of his third wife, Kathleen Savio, who was found drowned in a dry bathtub in March 2004.

The state police insisted for years that Savio was the victim of a freak bathtub accident but changed their tune after Stacy Peterson vanished.
