The Broward Sheriff's Office said 34-year-old Armando Alexander Guzman was found dead in a car near Fort Lauderdale Thursday morning from what appeared to be a self-inflicted gunshot wound.
A witness called 911 after noticing a bullet hole in the car's window and a person inside.
Guzman's daughter, 13-year-old Lourdes Guzman-DeJesus, was shot in neck on the way to school in Homestead on Nov. 20.
Authorities say a 15-year-old student pulled a gun from his backpack and fired it.
Eight other children, including Guzman's 7-year-old sister, were not harmed.
The student is charged with manslaughter and carrying a concealed weapon.
