Alfred Stewart, 31, was at the Ocean's Eleven Lounge in Hallandale Beach to celebrate a friend's birthday with a group of friends, all of whom are deaf, NBC Miami reported. The group was communicating using sign language, but a woman at the bar thought the group was making gang signs in her direction. According to police, 45-year-old Barbara Lee became angry and confronted the group, but they motioned for her to leave them alone. She then left the bar, before returning with two others — including 19-year-old Marco Ibanez. Mr Ibanez allegedly pulled out a knife and stabbed Mr Stewart, two of his friends and a bouncer, during a confrontation at the club.
