BREAKING NEWS !! From an anonymous source it has been CONFIRMED the MARCO POLO fire was started due to a LIGHTNING STRIKE !....the source of this information has been very reliable in the past. (see Rail cost estimates)....ALL you Monday morning armchair quarterbacks that seem to have the answers! why don't YOU conduct an investigation and come up with the CAUSE ? ANYONE driving by would be able to tell WHERE the fire started! HEAT RISES, flames go UP ! ......so by logic the fire showed itself stating in #2602. as for the experts stating that there isn't enough material in an apartment to show the type of flames that was exhibited I suggest you go to YOUTUBE and search fire behavior. It'll prove you wrong and lastly, finding the CAUSE is simple when there are clues left behind, thru the INTENSITY of heat and flames it's very possible the evidence you'd find in most common fire situations just may not be evident in this case.
