Investigators also have statistical data based on past crimes of this type that could provide a general profile of who may have committed the crime, Lanning and FBI profiler Clinton Van Zandt said.
Neither Lanning nor Van Zandt would provide an opinion on the Colorado case, saying each case is unique.
However, a 2006 report funded by the U.S. Department of Justice and compiled by Washington state Attorney General Rob McKenna determined
the majority of suspects in such cases are single and between 18 and 30 years old.
The study looked at more than 800 cases from 1968 to 2002, the latest figures available. It found nearly half the suspects were unemployed, and those who did have jobs worked in unskilled or semi-skilled labor occupations.
The report also said
21 percent of victims were 10 to 12 years old and initially encountered their abductor within a quarter-mile of their home. Jessica was 10 and last seen within two blocks of her house.
