Richard Paul White

A self-professed serial killer was indicted Thursday on charges of kidnapping, sexually assaulting and murdering two women whose bodies were found buried in the back yard of a Denver house where he once lived.

Richard White, previously charged in another slaying, also was charged Thursday with kidnapping and sexually assaulting three other women and trying to kill one of them.

White, 31, was charged in January with first-degree murder in the Sept. 7 shooting death of Jason Reichardt, 27, of Aurora. He has said that shooting was accidental.

While being questioned in Reichardt's death, White told police he had killed five prostitutes across the state since 1998, buried two in his back yard and scattered the bodies of the others in Costilla and Otero counties in southern Colorado.

Police found the bodies of Victoria Lynn Haskay, 34, and Annaletia Maria Gonzales, 27, in September. No bodies have been found in Costilla or Otero county despite extensive searches.

Gonzales was probably strangled, police said. Little information has been released about Haskay.

The 53-count indictment against White includes first-degree felony murder, sexual assault, kidnapping and other charges. He was being held in the Arapahoe County Jail.
