Topeka, KAN. (WIBW)--The Topeka Zoo is responding to the recent death of a gorilla. This follows months of controversy after a report questioned the zoo's care-taking abilities.

The gorilla, M' bili, was 17-years-old when he died this morning of unknown causes. And that age is well below the average life expectancy of 40 to 50 years for gorillas.

M' bilis death leaves one female gorilla, Tiffany, at the zoo.
