PHILADELPHIA (AP) — Investigators are looking into whether a 5-year-old who was playing with a lighter set a Christmas tree on fire, sparking a conflagration that killed 12 family members in a Philadelphia rowhome, officials revealed Thursday.
That disclosure was included in a search warrant application as city and federal investigators sought to determine the cause of the blaze, the city’s deadliest in more than a century, which took the lives of three sisters and several of their children early Wednesday.
