After all other leads have been exhausted, investigators may use specially developed software to compare the forensic profile to all profiles taken from a state's DNA database to generate a list of those offenders already in the database who are most likely to be a very close relative of the individual whose DNA is in the forensic profile . To eliminate the majority of this list when the forensic DNA is a man's, crime lab technicians conduct Y - STR analysis . Using standard investigative techniques, authorities are then able to build a family tree . The family tree is populated from information gathered from public records and criminal justice records . Investigators rule out family members' involvement in the crime by finding excluding factors such as sex, living out of state or being incarcerated when the crime was committed . They may also use other leads from the case, such as witness or victim statements, to identify a suspect . Once a suspect has been identified, investigators seek to legally obtain a DNA sample from the suspect . This suspect DNA profile is then compared to the sample found at the crime scene to definitively identify the suspect as the source of the crime scene DNA . </P>
