Ellen Trout Zoo officials are investigating the unexpected death of an 18-month-old giraffe. 

The giraffe, fondly known as “Slim,” was found dead by zookeepers Sunday morning, according to Ellen Trout Zoo Education Assistant Samantha Miller.

Slim was born at the zoo in the summer of 2009, Miller said.
