A third suspect has been arrested in connection with the alleged murder of Aspen native Nancy Pfister.

Katherine M. Carpenter, 56, was booked into Pitkin County Jail on Saturday. Details about her arrest were not immediately available, but a jail official confirmed that she faces charges of first-degree murder and conspiracy to commit first-degree murder.

The arrest comes after Carptenter called authorities, shortly before 6 p.m. on Feb. 26, to report a body found in a closet at Pfister’s home, located off of West Buttermilk Road.

On March 2, Deputies from Garfield and Pitkin counties executed a search warrant and removed contents from Carpenter’s employee-housing unit at the Christiana Lodge, located off Main Street in Aspen. The unit is owned by Alpine Bank, where Carpenter has worked for more than 20 years.

Two other suspects remain in custody in Pitkin County Jail on the same charges that Carpenter faces. William Francis Styler III and his wife, Nancy Christine Styler, were arrested at the Aspenalt Lodge in Basalt on March 3.

They had been renting Pfister’s West Buttermilk home.

In a post on her Facebook page, dated Feb. 6, Pfister, who was in Australia as the time, said that she was seeking a tenant for her home, and that “Kathy carpenter from alpine Bank will show anyone interested the ropes, watering greenhouse, Gabe’s stuff,etc. Very easy to contact me via email, thanks in advance!!!”

Three days earlier, on Feb. 3, Pfister said on her Facebook page that her West Buttermilk home would be available for rent “around” Feb. 22. Pfister said her current tenants — the Styler couple — are “not paying rent and they haven’t paid utilities.”

Meanwhile, prosecutor Andrea Bryan is expected to file formal charges of first-degree murder and conspiracy to commit first-degree murder against both Stylers in Pitkin County District Court on Monday. The date of Carpenter’s first court appearance was not immediately available.
