Three homeless people fall victim to a serial killer in Miami. Two victims were shot, two hours apart. One died. The other survived after police are alerted by a witness who flagged down an officer reporting a person with a head wound. The third victim was stabbed to death earlier in the year, and connected to the shootings by an officer who notice a link between the two. That link was a black vehicle. Willy Suarez Maceo, 25, a Miami area real estate agent, owner of the car, has been charged.
