Lethally Adorable Polar Bear Causes Death of Keeper

Well, sort of. The zoo keeper who hand raised the not-so-lovable fuzzball of a polar bear has died from a heart attack. First it was a panda bear who was his next door neighbor and now the curse of Knut has claimed another victim.

Berlin prosecutors said an autopsy Tuesday showed that the zookeeper who gained fame for hand-rearing the celebrity polar bear cub Knut died of a heart attack. The city's mayor paid tribute to him for writing Berlin history.

Thomas Doerflein, 44, was found dead in a Berlin apartment Monday. With the cause of death not immediately clear, prosecutors ordered an autopsy Tuesday.
