A child playing with fire reportedly was the cause of a closet blaze on the near northside Wednesday evening. Racine firefighters were called to what appears to be a two-story, single family home at 1231 Marquette St., just after 6 p.m. for a report of a fire. When crews arrived they found an adult had doused a fire in a closet with buckets of water. After a quick investigation, firefighters learned that the fire had been started by a child who had been playing with fire, according to a press release.
