We should pray for the 13 year old boy too. His injuries are similar to the 37 year old. Maybe it was the shooter's plan to wound a few people so they'd have to suffer. He's too good an aim. He intentionally shot these two in the mid-section imo. What does this professional psycho know about suffering unless he has battle scars, i.e. fighting in the mid-east and these are all paybacks on behalf of UBL.
If the guy was just a nut, he'd just off himself or do like the lady who killed her kids in Texas when she called and said she did it. Nut cases can have a break with reality but then they snap out of it or opt for suicide by cop.
This professional is on a mission and he's not acting alone. He's been through the training camp including advanced guerilla warfare.
