The search for Nancy Guthrie has entered its sixth week, with authorities warning that the person behind her disappearance could strike again.
Chris Nanos, the Sheriff, shared new details with NBC News, stating that investigators believe Nancy may have been targeted, but cannot rule out the possibility of another crime.
Nanos warned that 'criminal minds are criminal minds,' and that the suspect could 'absolutely' commit another crime.
Despite the uncertainty, authorities are hopeful that forensic evidence will help move the case forward, with officials looking closely at the 'mixed' DNA discovered inside Nancy's home.
The Pima County Sheriff's Department and the Federal Bureau of Investigation have not publicly named a suspect, and authorities have not confirmed if Nancy is alive or dead.
A $1 million reward has been offered by Savannah Guthrie and her family for information that could help 'bring her home,' with the investigation remaining active as the search for Nancy continues.
