ERIE, Pa. — There weren't enough working smoke detectors at a Pennsylvania home day care center where a fire killed five children, the fire chief said Tuesday.

State officials who inspect home day care centers do not check for smoke detectors, Fire Chief Guy Santone told a news conference Tuesday. But city authorities and state legislators are working on legislation that would make home day care centers register with the city, so it can deploy inspectors.

A message seeking comment was left with the Department of Human Services.

Santone said there was one detector in the attic of the day care center in the lakeside city of Erie.

Fire officials suspect the blaze that broke out Sunday morning at Harris Family Daycare was accidental, according to Santone. They are investigating whether it was an electrical fire.
