The Colorado Division of Wildlife says a necropsy on a mountain lion doesn't prove whether it was the animal that attacked a seven year old boy near Boulder, but officials remain confident they killed the right animal.
DOW spokesman Tyler Baskfield says that's based on evidence at the scene of the April 15th attack, including where the mountain lion was killed and tracking that placed the animal within 30 yards of the attack.
Shir Feldman suffered a broken jaw and puncture wounds.
He and his family were taking a short hike on Flagstaff Mountain and were within 50 yards of the parking lot.
A protein test was used to search for human blood on the five year old female mountain lion's claws and mouth, but no blood was detected.
The animal was 84 pounds and in excellent condition.
Rabies tests were negative.
