There’s a story blowing up on Twitter right now about a Colorado man who reportedly fought off and killed a mountain lion that attacked him while he was out for a trail run:

NBC News, Reuters, The Daily Beast, and just about every other outlet you can think of is covering it. But the headlines, including this one from Colorado Parks and Wildlife, don’t tell the entire story…

The mountain lion was actually a juvenile but CPW doesn’t say how young or how big it was:

As wildlife officers searched the trail area provided by the runner, the body of a juvenile mountain lion was found within feet of several possessions that the victim asked the officers to look for on the trail. The lion has been taken to the Colorado Parks and Wildlife animal health lab for a necropsy.

Officials are calling it a case of self-defense:

“The runner did everything he could to save his life. In the event of a lion attack you need to do anything in your power to fight back just as this gentleman did,” said Mark Leslie, Colorado Parks and Wildlife Northeast Region manager.

And according to CPW, the runner didn’t even use a weapon to kill the mountain lion:

So, how much did the juvenile animal weigh that a runner was able to kill it with what sounds like the use of his bare hands? More information, please.
