Judge in Colo. Philanthropist Murder Sets April 23 Hearing Date

— -- Three people arrested in connection with the death of Aspen philanthropist Nancy Pfister will be back inside a Colorado courtroom later this month after a judge today said she was concerned that the case was not moving forward.

Judge Gail Nichols was expected to set the date for the crucial preliminary hearing in the case today, but postponed her decision after defense lawyers argued they needed more time to analyze evidence.

"We have almost a terabyte of discovery," said Tina Fang, the attorney for William Styler. "It's an incredible amount of information."

Nichols indicated that she will set the preliminary hearing date during the next court appearance on April 23.

Some of the evidence against the suspects is expected to be revealed publicly during the preliminary hearing. Until then, court documents will remain sealed.

Pfister, 57, whose late parents co-founded the popular Buttermilk ski area west of Aspen, was found severely beaten in her mountain home on Feb. 26 after returning from an extended trip to Australia, authorities said.

Pfister's friend, Katherine M. Carpenter, was arrested last month and charged with first-degree murder and conspiracy to commit first degree murder.

William F. Styler III, 65, and his wife, Nancy Styler, 62, have also been charged with first-degree murder and conspiracy to commit first-degree murder.

William Styler was brought into the courtroom in a wheelchair, followed by Carpenter and Nancy Styler.

Each has been appointed separate attorneys and is being held in a separate county jail.

It was Carpenter who made the 911 call around 6 p.m. on Feb. 26 to report finding Pfister's body in the upstairs master bedroom closet inside her home.

Pfister wrote in late January and in early February on Facebook that the Stylers, who rented the home for about three months, had not been paying rent or utilities and that she was seeking new tenants.
