Three people are dead after a standoff ended early Friday at a recreational-vehicle park in Deerfield Beach, Fla., near Boca Raton. The ordeal began Thursday night when an emergency call was received about a shooting at the park. According to early reports, police found a man who had been shot lying the ground. Meanwhile, inside the RV, another man holed up with the two children and a woman. When police entered the RV seven hours later, the woman, along with her 7-year-old son, were badly hurt and the man and the 9-year-old boy were both dead. The man outside the RV, who authorities said did not know the shooter, eventually died as well. The identities of the people involved have not been released and it's not clear what triggered the incident.
