MILWAUKEE (CBS 58) -- Updated information from the Milwaukee Fire Department shows reports that smoke detectors were operational in the apartment that caught fire on Friday, Feb. 21, but that the cause of the fire was accidental as space heaters being too close to combustibles led to the blaze.

One person was evaluated for smoke inhalation, and one cat was reported missing, while 16-people self-evacuated and four people were rescued.
