On the late night of Monday, November 10, 2025, 34-year-old Casey Sheehan Kneisel was fatally shot after a violent sequence that began at a residence on Tucson’s west side. Kneisel and a woman were both shot at the home; Kneisel ran to the nearby McDonald’s at Silverbell Road and Grant Road seeking help, but the assailant pursued him into the restaurant and shot him there. A shattered glass window at the McDonald’s marked where the violence continued and police tape sealed the scene while investigators worked.

The woman from the residence was taken to a local hospital for treatment. The Tucson Police Department opened a homicide investigation and quickly arrested a suspect identified as 35-year-old Philip Michael Chambers Jr. The community reacted with shock and concern after a routine fast-food restaurant became the site of a fatal public shooting.

Anyone who was in the area that night or who may have information about either the residence shooting or the events at the McDonald’s is asked to come forward.
