A Florida zoo official says an employee who was killed by a tiger earlier this month didn't follow zoo policy.
Palm Beach Zoo CEO Andrew Aiken said in a statement posted Friday on Facebook that zoo policy prohibits zookeepers from entering an enclosure to which a tiger has access.
Stacey Konwiser, 38, was killed April 15 when a male Malayan tiger attacked her in the enclosure known as the night house, where tigers sleep and are fed. Aiken said Konwiser entered the part of the night house "after it was clearly designated as accessible by a tiger."
Aiken said five investigations are underway into the incident.
The zoo's Facebook page says "zookeepers are never to enter into an enclosure when a tiger is present or has access to the enclosure."
