hallway, away from the shooter's door with his back turned. >> as door is closing and it's so heavy, it will slam. i'm walking down this way. and i believe that's what caught the shooter's attention. as i was walking down, i heard rapid fire. and at first, i took cover. i felt a burning sensation. i went to go lift my pant leg up and i saw the blood. >> police say the shooter had fired about 200 rounds through his door at campos. how lucky is he that he gets hit once? >> absolutely lucky. that's a straight shot, what we used to call a fatal funnel. it's just a hallway. he's so lucky he was able to duck into one of these cubbyholes. a lot of hotels just have flat walls and then a door.
