Hopefully better news on this update from RI:
"UPDATE:
Just spoke with a friend of the family who said that Sean lost a substantial amount of blod and the bullet traveled near the femoral artery, which is located in the thigh. Sean's father, Pedro, the chief of police in Florida City, Florida, is with him at the hospital, according to the source. They believe the situation is stabalizing, and are obviously hoping for the best."
