Summer Moody Shot for Practically No Reason

al.com reports

Two men staying at a camp on the back side of the island heard a door being broken. One of the men, according to Mack, was a caretaker of the property, knew of several recent break-ins and went to investigate. 
The men discovered intruders and fired once each, Mack said. 
Apparently, he said, Moody was hit by one of those shots. He said that a bullet from a small-caliber rifle struck her "toward the back of the head." 
Mack said investigators believe that Moody was outside some feet away from one of the camp houses, although her exact location and exactly what she was doing had not been determined.

What's your opinion? They're comparing this to the Trayvon Martin case, but I don't really see the similarity. In this case there was no hint of aggression on the part of the teenager, in fact, I can see no reason at all for shots to have been fired.
