Police were called out to a report of shots fired near Northwest 213th Street and Ninth Court -- just south of the Miami-Dade/Broward county line.
Officers couldn't find anything at the scene when they arrived.
A few minutes later and a few miles away, at NW 199th Street and 27th Avenue, someone in a dark car stopped at a Florida Highway Patrol checkpoint and told troopers his passenger had been shot. Troopers called paramedics, who rushed the man to the hospital, but he died from his injuries.
Are the two incidents related? Police say they're not sure. Miami-Dade homicide detectives are trying to piece together the puzzle.
