"HARTFORD, Conn. April 8 ?
A 39-year-old retarded man who liked to dress up like Batman and tell neighbors he was a crime-fighter was beaten to death in the lobby of an apartment building where he had been placed by state officials.
Ricky Whistnant died at the scene Saturday. He fell and hit his head on a radiator after three teens pelted him with bottles of soda he had just bought, authorities who viewed a security video of the attack said. Even after Whistnant collapsed, police said, the boys continued kicking and pouring soda on him.
The attackers fled after tenants called 911, but several hours later police arrested two 14-year-old boys and one 13-year-old."
