The park will be closed until further notice due to the "aggressive" mountain lion seen in the area, the Department of Parks and Recreation said in a news release.

The boy's bite wounds were swabbed for DNA to try and match it to a known cat. In the meantime, authorities are searching for the mountain lion.

AIR7 HD was over the area as authorities attempted to lure the mountain lion out of the hills with a deer carcass.

If the mountain lion is found and the DNA matches up with the boy's bite marks, there's a good chance the animal will have to be killed.
