In July of 2015 a Southwest African Lion named Cecil who lived in the Hwange National Park in Zimbabwe was killed by Walter Palmer, an American trophy hunter. Cecil was a favorite of park visitors and was being tracked and studied by scientists. There was an angry public response to Cecil's death and as a result Palmer had to leave his dental practice in the U.S. for a period of time.
The lion was shot with an arrow outside the park. It's believed that he was lured out of the park, shot, and then tracked for 40 hours before being killed. Palmer had a permit to kill a lion and wasn't charged in the incident, but his two Zimbabwean hunting guides were charged.
This incident brought international attention to the effect of trophy hunting on declining lion populations. The U.S. Fish and Wildlife Service now lists the Southwest African Lion on the endangered list and their body parts may no longer be brought into the United States.
