Authorities in Arizona are conducting a manhunt after a woman was sexually assaulted during a home invasion near the site connected to the disappearance of Nancy Guthrie, the mother of NBC anchor Savannah Guthrie. The Pima County Sheriff's Department, which is leading the Guthrie investigation, is also pursuing the suspect behind this separate Tucson attack, with the two cases emerging in close proximity to one another.

The development comes as the search for Nancy Guthrie continues following an anonymous tip pointing to a possible shallow grave near the Nogales border. Investigators checked the location but did not find her, and the Pima County Sheriff's Department has confirmed that its investigation into her disappearance remains active.
