INSTINCT AND TRAGEDY: Nancy’s loyal dog breaks free, runs 5 kilometers toward the Rillito River — officers are left stunned when they find it frantically digging at a freshly covered patch of earth

Officials cautioned against speculation regarding the dog’s behavior, noting that while the development is considered significant, forensic confirmation is required before drawing conclusions. Laboratory analysis of soil samples and any materials recovered is currently underway.

The investigation remains active as authorities continue processing both physical evidence and geographic data associated with the river corridor area.
