A couple in Colorado was arrested on Monday in the death of Nancy Pfister, an Aspen socialite whose body was found in a home they rented from her, the New York Daily News reported.

William Francis Styler III, 65, and Nancy Christine Styler, 62, were charged with first-degree murder and conspiracy to commit first-degree murder, according to the sheriff's office.

Pfister, 57, was the daughter of the late Betty and Art Pfister, who co-founded Buttermilk Mountain -- host of the Winter X Games several times. 

According to officials, the Stylers were renting a home owned by Pfister as she vacationed in Australia. However, it seems on Pfiser's Facebook page that she was not content with her current tenants.

"Hi everyone I'm still in Australia and I'd like to stay in Australia but the people that were supposedly taking care of my house are not doing what they said they would do," she allegedly wrote on January 21. ""...if you have any ideas how to help me get someone in the house around February 22 it (sic) be great thank you!!!!"

Though the Facebook post did not mention names, Pfister claimed they weren't paying rent or utilities and weren't taking care of her dog, Gabe, which she said gave them a discounted rate.

Pfister returned from her vacation on Feb. 22, the same day that the Stylers ended their one-month stay in her home. On Feb. 26, Pfister's body was discovered in an upstairs closet. 

The official cause of death has not been released by authorities.

Both Stylers are being held without bond.
