Anne Frank died in the infamous Bergen-Belsen camp in 1945.

She was just 15-years old at the time, but her famous diary which documented her struggles of living in hiding with her family in a single room during World War II lives on forever. The teenager lived with her family in a secret room for 2 years before being discovered by the Nazis and sent to a concentration camp... But the question that has remained unanswered is who told the Nazis the Frank family were living there for so long unharmed? According to a new study, the family not have been betrayed by a friend but rather just got found out by chance. At The Anne Frank House museum, researchers have reportedly found that the Nazi raid on Anne's house could be over coupons for rationing of food. On the 10th of March 1944, Anne wrote about the arrest of two men who supplied the family with ration cards...

"‘B and D have been caught, so we have no coupons…"

But what's more interesting is that police records from the day the family were discovered by two men on August 4th 1944 show that the pair were never hired to hunt Jews down. Also the raid on the house is said to have taken two hours -much longer than a raid would take if you were tipped off and knew exactly what you were looking for. Who actually sneaked out the Frank family to the authorities? It doesn't look like we'll know for certain.
