Latest figure in the 10-day-old mystery was Mrs. Marilyn Hudspeth Lancaster, 21, who worked in a Byers grocery store for several months before she took a bus for Amarillo, Tex., March 6 to visit a friend and vanished on the way back. Undersheriff Tom McDaniels of Araphahoe county reported the story of the girl's disappearance to Sheriff Art Everson of Boulder, who asked him to aid in the investigation.

McDaniels said descriptions of Mrs. Lancaster and the murder victim tally to a T. The girl found in the canyon was 17 to 20, 5 feet, 3 inches, 100 pounds, had shoulder-length, wavy reddish-blond hair, an appendectomy scar and perfect teeth.

IN BYERS 10 MONTHS
Friends of Mrs. Lancaster described her as about 5 feet 2 inches, 100 to 105 pounds, with long, reddhish-blond hair and good teeth. A Byers woman said Mrs. Lancaster told her she had had her appendix removed.

McDaniels said friends also said the missing girl was well-groomed and meticulous about her hair and nails. Although the murder victim had been savagely beaten and her features ravaged by animals, an examination showed she had taken good care of her hands and hair.

A check showed Mrs. Lancaster had arrived in Byers about 10 months ago. McDaniels said she came with two men, one of whom she said was her husband, Charles Lancaster, and the other her brother, Charles Robbins.

She had been married before, probably twice, and received phone calls from Amaraillo from a man who called her Marilyn Hudspeth. She also received maonthly Air Force allotment checks from Amarillo in that name.

McDaniels learned the brother left last fall and didn ot return. He said the husband worked for a time on an oil rig near Kit Carson, went to Philadeplphia early this year, came back for a few days and then left again. He has not been sen in Byers since.

Neighbors believe Mrs. Lancaster indentded to return by the fact she took only an overnight bag and left an apartment full of furniture, including a television set, her clothes and other personaal belongings. She also left a number of pets of which she was very fond - a dog, Ace, cat, Kitty Puss, three rabbits, Thumper, Stinky and Baby, and two parakeets.

PLANNED SHORT TRIP
A Byers woman said Mrs. Lancaster asked her to drive her to Strasburg March 6 to catch a bus for Amarillo and asked her to care for her pets while she was gone. She promised to be back Monday, March 8.

McDaniels said neighbors became disturbed about Mrs. Lancaster when phone calls from Amarillo started again a week ago. The caller asked for Marilyn Hudspeth and appeared puzzled by the fact she had not yet arrived in Byers.

The calls were made to the grocery store, McDaniels said, and indicated Mrs. Lancaster had arrived in Amarillo and had started back on schedule. A check showed she had never arrived in Strasburg or Byers.

McDaniels said Mrs. Lancaster also left a 1946 Buick in the garage in Byers and a number of personal papers, including those from her divorce. Her birth record showed she was born July 27, 1932, but friends said she was so slender and dainty she could easily have passed for a girl in her teens.
