Man Convicted Of Aspen Socialite's Murder Found Dead In Prison Cell

FREMONT COUNTY, Colo. (CBS4)- The man who was convicted of murdering Aspen socialite Nancy Pfister was found dead in his prison cell on Thursday.

William "Trey" Styler III, 67, pleaded guilty to second-degree murder and received a 20-year prison sentence as part of a plea deal in Pfister's murder.

In learning of his death, Nancy Styler said in a statement, "Trey is now at peace after being tortured for such a long time. He was a successful, brilliant doctor, incredible and loving husband and father, and a gentle man. I hope people will remember him for the man he once was before his physical and mental illness took over his life."

Investigators initially believed Styler couldn't have acted alone in Pfister's killing because he suffers from a disease that deteriorates his lower body, making it difficult for him to move a body by himself, the paper reported.

The Stylers rented Pfister's Aspen home for several weeks over the winter and had hoped to open a spa business. The affidavits pointed to a bitter financial dispute between the Stylers and Pfister, which police say led to Pfister's Feb. 24, 2014 murder. She was found dead in a closet in her home two days later by Carpenter.
