VIDEO: A former Northern Arizona University professor faces multiple federal charges of stalking or making false statements against at least 11 people, including several members of two hotshot firefighting crews. Melissa Ann Santana, who at the time was an associate professor of interior design, allegedly sent threatening messages to three hotshot crew members, an NAU student and others, according to a federal complaint filed in U.S. District Court in Coconino County in late October. At least one of the men told federal investigators he had a relationship with her that ended; others met her online and some of the alleged victims were family members of men she met.
