-Woman with family ties to Germany and a son in the German navy who probably knew in general terms that something strange was going on at the warehouse where her husband worked. Had she wanted to betray them, she probably would not have waited two years to do so.
-Employee at the warehouse known to have stolen merchandise from it, and would have known that a back portion was suddenly sealed off. People who knew him said that while he was a thief and a braggart, he was not the betraying sort. Also, why wait two years?
They also looked hard at a new suspect: A former business acquiantiance of Anne's Father- a known low life, had been briefly arrested after liberation for suspected collaboration. The guy and a pair of brothers were also suspected of running a protection scheme during the war that was directed at jews. Before the family went into hiding, he had shaken down Otto Frank on one occasion for some spending money. The investigators did determine that rumors that he blackmailed Frank after the war were false, but could they did not clear of him of being the betrayer.
In the end, the investigators concluded that it could have been anybody. Not only were there the "usual suspects" and the new one, they or another worker might have told a friend about it. In addition, the area was densely populated and long time residents could well have noticed that the "door to window" ratio had a gap, or it could have been somebody passing through who saw somebody at a window.
The investigators also emphasized that the betrayer need not have been a Nazi or German sympathizer, but could also have been a-political or even a politicaly pro allies but culturally anti semitic individual.

During Soviet times, the Communist regime did not distinguish victims. Everyone was lumped together as victims of Nazi murder and mayhem. Since the dissolution of the USSR, things are beginning to change in this regard and the Soviet archives regarding the Holocaust are now available to all researchers. There is a new (2010) Jewish museum in Moscow (it is huge and very high-tech) that has a large section devoted solely to the Holocaust.
