Questions after deadly fire claims two on Detroit's west side

After the flames were out and the smoke cleared away, investigators went to work to try and determine how a fire started and whether it was an accident or arson.

We've learned the bodies of 67-year-old Bobby Cross and his stepson, Darryl Sims, were found in the hallway.

The small ranch home didn't have smoke detectors, but it's believed the two must have been awake and were trying to escape the flames.  Simms suffered a stroke and the men may have been trying to help each other out of the house, but didn't make it.

Cross' longtime companion and Sims' mother left for work shortly before the fire broke out Monday around 6:00 a.m.  She said there was another guy in the house.  He would live with them from time to time.  She didn't know if he had anything to do with the fire, but family members told us the man argued with Cross recently about money.

While detectives search for answers, family members returned to the home to salvage memories in the soot covered debris.

Neighbors tried to save the two men, but they couldn't reach them in time.  They wonder if the firefighters would have arrived sooner would the two men still be alive.  So many questions that even if they are answered will never fill the void of the men's tragic deaths.
