Updated (Thursday 8/06/2015 5:40pm): Convicted murderer William “Trey” Styler was found dead in his cell Thursday. Styler was serving a twenty year sentence for killing Aspen native Nancy Pfister. A press release from a public relations firm, sent out Thursday afternoon, announced Styler’s passing, saying the 67-year-old was found hung to death. The Colorado Department of Corrections later confirmed he had died.

An investigative report by NBC about the Nancy Pfister case will air tonight, Friday October 10th, at 7pm Mountain Time. The two hour long Dateline special includes unusual interviews with former defendants Kathy Carpenter and Nancy Styler. Network reporter Keith Morrison says the characters in the case made it worth an extended look at what happened before and after Nancy Pfister died earlier this year.

Judge Gail Nichols, in Aspen, has released some of the details in why law enforcement originally arrested three people this spring in the death of Aspen native Nancy Pfister. One of the three, William "Trey" Styler, confessed last month to murdering her in February. But questions continue about why Styler's wife, and a long time local, were also held for months without bail on murder charges. 

There have been major developments in the Nancy Pfister case this week. First the District Attorney’s office decided to drop charges against one of three murder defendants. Now, it’s considering doing the same for another defendant, who’s scheduled to appear in court Friday morning.
