WELLINGTON, Fla. — Editor's Note: The above image is a file photo of a different giraffe.

The giraffes were named Lily and Jioni, and they lived at Lion County Safari in Wellington, Fla. They were killed in early May, but the cause of death was not determined until now, CBS affiliate WPEC reports.

"The keepers and our whole team were understandably devastated by this sudden and tragic loss; out of respect for their mourning and the pending pathology results, we waited to share this information," the park said on Facebook.
