Three men have been arrested in connection with a shooting in Pompano Beach late last month that killed a 16-year-old boy and injured three other people. A group of people were standing outside of a business at 1780 Dr. Martin Luther King Jr. Blvd about 5 p.m. on March 25 when multiple people approached them and started shooting, according to the Broward Sheriff’s Office. John Zetrenne, 16, of North Lauderdale, was found injured, lying on the sidewalk outside the business when deputies and Pompano Beach Fire Rescue arrived, the Sheriff’s Office said.
