Steven Brown, a 32-year-old black man, died Saturday, May 21, four days after he was beaten in the 600 block of Cerritos Avenue in Long Beach, according to Los Angeles County coroner's records.

Officers responded to a call reporting a man found unconscious in a driveway about 7 a.m. on May 17, according to a Long Beach Police Department news release.
