On December 18, 2023, 62-year-old Carmen Buscemi, a male master mechanic and owner of an auto shop near 27th Avenue and Deer Valley Road in Phoenix, Arizona, was fatally shot during a domestic violence incident. The shooting occurred around 11 a.m. when 53-year-old Bryan Fitz arrived at the shop and opened fire, also shooting his estranged wife, 49-year-old Sage Fitz, who worked as the shop’s secretary. Sage Fitz was taken to a hospital and later died; Buscemi was pronounced dead at the scene.

After the attack at the shop, Bryan Fitz drove to his home near 23rd Avenue and Utopia Road, where he fatally shot his 12-year-old son, Baynen Fitz, and the family dog before dying of a self-inflicted gunshot wound. Phoenix police concluded the motive stemmed from a marital dispute after Sage Fitz had recently decided to seek a divorce, and family members described Bryan Fitz as increasingly controlling after a disabling motorcycle accident. There are no arrests, and authorities are not seeking other suspects.

Did anyone who knew Carmen or worked at that shop notice any changes at the business or concerning interactions in the weeks before December 18, 2023?
