MIAMI – A southwest Miami-Dade man has been arrested for a deadly shooting over the weekend that left his tenant dead.

Samuel Gonzalez, 34, is charged with second degree murder.

According to police, Gonzalez rented an efficiency on the side of his home at 1925 SW 125 Court to 27-year-old Armando Alvarez and his girlfriend.
