Florida man, 7-year-old son shot dead in Miami

Authorities in Florida say a man and his 7-year-old son were shot dead and found inside a pickup truck in a Miami suburb.

Miami Gardens Police Department said Monday in a statement that they are investigating the murder of 31-year-old Lavel Mucherson and his son Hezekiah.

Detectives told local news outlets they believe it was a "targeted" attack.

The Miami Herald reports Mucherson was arrested in 2014 on a charge of second-degree murder. But the Miami-Dade State Attorney's Office concluded three years later that Mucherson could have acted in self-defense.

A judge granted him immunity under Florida's self-defense law.
