The Toledo Zoo on Friday announced the death of Binti, a 1 1/2 year old female giraffe.
The giraffe was found down and unable to stand in the indoor giraffe holding area on Tuesday morning.
Zoo personnel took a blood sample from Binti and found "multiple severe abnormalities and euthanasia was elected to prevent suffering," zoo officials said.
A full necropsy was performed and results are pending.
