From the piece:
Terrance Ervin Daniels, 45, was brutally attacked "in the upper body" with a kitchen knife on Jan. 9 in Burlington, N.C., while he and another deaf friend were signing to each other while walking down the street.
Suspect Robert Jarell Neal, 22, saw the men and "mistook the sign language for gang signs," Sgt. Mark Yancey of the Burlington Police Department told ABCNews.com.
