TUCSON, Ariz. (AP) -- Arizona Game and Fish officials are investigation the death of one of the more than 30 desert bighorn sheep recently released in Tucson's Santa Catalina Mountains.
The 4-year-old ram was found dead Wednesday by Game and Fish staff along the eastern edge of Sutherland Ridge near the headwaters of Romero Canyon.
The discovery was made after a signal from the sheep's GPS radio collar was detected during an aerial survey.
Samples have been collected from the carcass for analysis.
Game and Fish officials say possible causes of death are injuries that may have occurred during or after capture, including stress that can lead to heart failure. Other possible causes are a fall, a predator or disease.
The ram was captured Nov. 16 near Yuma and released two days later.
