Bob Joseph/WNBF News [December 1, 2014][/caption]Binghamton fire department investigators have finished their probe into the cause of a two-alarm blaze that tore through a downtown apartment building.

Officials say they have been unable to determine how the December 1 fire at 26 Stuyvesant Street started.

Although no people were hurt, two dogs died as a result of the blaze.

Investigators say there remains "more than one" possible cause of the fire that left four people homeless.

The early-afternoon blaze caused heavy damage to the two-story structure. It was reported about 15 minutes after police were called to a home invasion incident about a block away.

In that incident, several people forced their way into a Rutherford Street residence. A woman who lived there was injured.

Because the two incidents happened around the same time and in the same neighborhood, police and fire investigators tried to determine whether they were related.

Although several people were interviewed, the investigators say they did not establish a link between the fire and the home invasion case.
