“When police arrived on scene they spoke with a female who had heard gunshots inside the residence while she was preparing breakfast in the kitchen. It turns out that we have an 11-year-old child who is deceased and a man in his 40s, who is also the child’s father, is also deceased,” said Davie police Lt. Mark Leoni.

Police said the mother told them her daughter had a debilitating terminal illness which is a “possibility as to why this tragic incident occurred.”
