Palm Beach Zoo has had other tiger incidents

WEST PALM BEACH, Fla.-- As the zoo where a longtime keeper was killed by a Sumatran tiger, documents released by the Florida Fish and Wildlife Conservation Commission dating back to 1990 reveal other tiger incidents at the zoo.

The Palm Beach Zoo said Monday it does not blame the male Sumatran tiger -- one of only 250 believed to exist in the world -- for Stacey Konwiser's death, and that they expected nothing to happen to the animal.

CBS affilaite WPEC in West Palm reports that documents show an February 1990 in which a hired maintenance man got attacked by a monkey. The monkey bit the worker on the back of his hand.

In February 2008, a tiger at the Palm Beach Zoo bit the tip of the finger of a zookeeper. Susie Nuttall and another employee, according to the report, were training two male tigers, Mata and Rimba, in the night house, the same place Konwiser died.

The tigers were in separate cages when Nuttall was nipped by Mata as she fed the animal a reward. Nuttall, who had eight months of experience at the zoo, needed stitches to close the wound. The zoo, according to the report, no longer allowed hand feeding.

In May 2011, investigators said a maintenance worker entered a restricted area to retrieve a DVD. One of the tigers jumped on the mesh of the enclosure and caused minor injuries to the worker's back.

The latest tiger attack is under investigation. The zoo was last inspected in January. No violations were found.
