A 20-year-old man was killed after he entered a tiger enclosure at the Copenhagen Zoo Tuesday evening. Zookeepers arrived Wednesday morning to find what was left surrounded by three Siberian tigers. Police have no idea why the man broke into the tiger facility but have not ruled out suicide as a possible motive.

Good call police.

Family members reacted in shock and in disbelief, telling the Danish newspaper Ekstrabladet that the as yet unidentified individual was a “… really, really nice guy,” according to the Daily Mail.

A post-mortem examination revealed that the man had been bitten on the throat, face, chest, and thighs. Superintendent Lars Borg said, “The tigers attacked him and killed him. It is likely that a bite to the throat was the primary reason for his death.” Borg added, “He has been in the water and the animals must have seen that and attacked him.”

Siberian tigers are the largest members of the cat family with males often exceeding 500 pounds.
