Knut died on Saturday!

this cute polar bear was reported dead on Saturday. Berlin's beloved polar bear--Knut, he is only 3 years old. He is so young compared to the normal living age of 15. Knut and his brothers were rejected by his mother when he was born. The zookeeper( see in the picture) hand-raised him and treated him as his own son. This cute polar bear became the star of Berlin Zoo, and attracted lots of money for them. Knut's father--the zookeeper died 2 years ago, and he was died on Saturday without any warning.
"
A post mortem will be conducted on Monday to try to pinpoint the cause of death, he said.
Between 600 and 700 people were at Knut's compound and saw the four-year-old bear die, German news agency DAPD reported.
One visitor said she watched Knut lying on the surface of the water motionless with only his back showing for ten minutes until zookeepers came and fenced off the compound."
This is so sad news....He is so cute and so young. maybe he just missed his father too much... : (
