CUSTER, S.D. (KSFY) - Two Custer State Park burros have been put down after being injured in the Legion Lake Fire last month.
According to a press release from Custer State Park, veterinarian staff put them down humanely after determining they would not recover from internal and external injuries causing organ failure.
The park said the remaining six burros continue to receive daily treatment and monitoring as they are still in the critical phase of recovery.
They are being held in an off-site, indoor facility until they make a full recovery.
Officials say the Legion Lake fire started on December 11 and was caused by a downed power line. It burned more than 53,000 acres, making it the third largest wildfire in Black Hills history.
One burro died due to the wildfire, along with an elk and several deer.
