The search may have been complicated from the outset, however, as worried neighbors summoned by the girl's parents walked through the house and grounds before police arrived, according to law enforcement sources. After Elizabeth's 9-year-old sister told her parents that Elizabeth had been taken away by a gunman, they "contacted several neighbors and then contacted the police," according to the initial Salt Lake City police report. Those anxious neighbors may have arrived at the home up to 45 minutes before police were called, and their efforts may have compromised the evidence, authorities said.
