Years ago, Huntsman baby-sat the Hawker grandchildren and they were friendly with each other.

"It makes us so sad, we want to cry," Kathie Hawker said. "We enjoyed having them as a neighbor. This has just blown us away."

Aaron Hawker said he talked with West on Saturday morning. He told Hawker he was cleaning out the mess in the garage.

"Two hours later, suddenly we had all these policemen here," Aaron Hawker said.

Fred Newman, a neighbor whose cousin is the husband's mother, said he's perplexed how the three oldest daughters living there didn't know about what police say was going on. He said the girls didn't always park their cars in the garage, but did sometimes in the cold winter months.

He said he has used his snow-blower to clean off the driveway of the home and the young women would thank him.

The girls were normal youngsters, coming and going often, neighbor Vickie Nelson said.

"It's shocking and kind of morbid and strange," Nelson said as he looked across the street at the garage from her from lawn.

Roberts said the case has been "emotionally draining" and upsetting to investigators. He was at the home when the bodies were discovered.
