Police make third arrest in murder of Colorado socialite
Kathy Carpenter, 56, was being held without bond pending the filing of first-degree murder and conspiracy charges in the killing of Nancy Pfister, Pitkin County Sheriff Joe DiSalvo said in a statement.
Pfister, 57, whose late parents co-founded the Buttermilk Ski area west of town, was found slain inside her Aspen home on Feb. 26.
Five days after the discovery of Pfister's body, police arrested William Styler, 65, a retired physician, and his 62-year-old wife, Nancy, on first-degree murder charges.
Authorities have not said how Pfister died, nor disclosed a possible motive for the slaying. It is the first homicide case in Pitkin County since 2001, the sheriff's office said.
The Aspen Times newspaper reported on Saturday that Carpenter worked at a local bank and was the one who discovered Pfister's body.
The Pfister family is well known in Aspen, a tony ski resort town that is a getaway for Hollywood celebrities and other wealthy visitors.
The Stylers will be formally charged on March 17, the sheriff said, and Carpenter will make her first court appearance the same day.
