when there was another student struggling in the class, they turned to martin to help tutor him along. a quiet but compassionate kid and someone who was a leader. >> we don't want to do anything to intrude on the family's privacy, but martin's mom and sister are also in the hospital. >> yeah. i'm sorry to say that denise, his mom, took a wound to the head with shrapnel, and she's been in surgery. and his little sister janie, wonderful, sweet girl, also lost a limb. lost a leg. >> and she just started dancing. >> yeah, she's an irish step dancer, loves it, and everyone said if anybody is going to bounce back from this, it's janie. she's a pistol, a tough kid, energetic. i don't think her dancing days are over. >> i certainly hope not. i know we haven't talked to martin's dad, but the family, it's -- they'll never be the same, obviously.
