Origins: Although we're still not quite sure about these photographs, according to Steve Richards, who wrote a couple of articles about them for Western Mule Magazine, these pictures date from 2002 or 2003 and show Berry, a now 11-year-old mule, owned by a 25-year-old hunter named Jody Anglin. The incident depicted took place in southwestern New Mexico, and came about as Berry the mule grew more aggressive over time in his pursuit of mountain lions with Jody:
When Jody first got the mule and after Jody shot the first lion out, Berry casually came over to the lion and just nuzzled the lion and casually nibbled it. With each lion Berry just got more aggressive. Jody said it didn't take more than two lions and Berry got really aggressive to the lion and couldn't wait to get the cat.
