Friends of Richardson told the newspaper that there had been a scuffle between Richardson and a group of men earlier in the night, after the men tumbled down a hill and ran into him and his friends.

"The guy threw the hat back at him," one of Richardson's friends told the newspaper. "And when [Richardson] caught it, the guy hit him in the face and [Richardson] hit the ground and hit the concrete with the back of his head. He just collapsed."

Richardson, who suffered severe brain damage, was declared dead two days after the incident, and his organs were donated.
