"Cambridgeshire zookeeper killed by tiger was a 'shining light'"
On 29 May 2017, Rosa King (a zookeeper) was killed by a tiger in Hamerton Zoo Park.
"The council has opened an investigation into the cause of the tragedy.
One theory is that a steel safety barrier to separate tigers and staff either malfunctioned or was left open due to human error."
Should the tiger be killed?
