Police investigate "suspicious" vulture death at Dallas Zoo

An investigation was underway Saturday into the suspicious death of a vulture at the Dallas Zoo. It comes just over a week after a clouded leopard at the same zoo went missing for several hours after her enclosure appeared to have been tampered with.

Dallas police told CBS News in a statement that officers were called to the zoo Saturday after the vulture was found dead in its enclosure.

In a separate statement provided to CBS DFW, the zoo said that staff discovered the vulture dead in its Wilds of Africa habitat under "unusual circumstances."
