Dr. Steve Wilson of the Glenwood Animal Hospital in Tyler tells the Tyler Morning Telegraph that Chico weighed more than 14,000 pounds. Wilson cared for Chico while he was at the Tyler zoo -- from 2003 until his death.
Chico came to Tyler from the San Diego Zoo.
Caldwell says Chico died suddenly and there were no signs of illness.
A necropsy has been performed but Caldwell says the cause of death is still undetermined, pending further test results.
