BRIDGEPORT - Three months after an apartment fire killed four, the City of Bridgeport says it is working to improve safety at that housing complex.

Tiana Black and her three children were killed in the fire at the PT Barnum Housing Complex.

Bridgeport?s housing director says the city has gone into the public housing complexes, conducted safety inspections and corrected 150 disabled smoke detectors. Long-term solutions include rope escape ladders and specialized smoke detectors.

However, the city says it is waiting on the state to find out exactly what caused the fire before anything more can be done.
