COLLIER COUNTY, Fl.- The remains of sibling 4-month-old panthers were found on Immokalee Road, near the entrance to Bonita Bay Club East Sunday.

The Florida Fish & Wildlife Conservation Commission said the panthers were hit by a car. The remains were found on Immokalee Road, near the intersection of Wildwood Boulevard.

FWC initially sent a release stating one panther had been found. Later Sunday, FWC received another call about a second panther in the area. Officials believe the second panther was likely there earlier Sunday, but they did not see it. Officials could not determine the sex of the second panther because it had been repeatedly run over.

16 panthers have been killed on roadways in Florida this year. Both panthers are being taken to the FWC Gainesville lab for a necropsy.
