The victim reported being followed by a black truck, which opened fire at their car at the intersection of Park and North I streets, though no injuries were reported. Police located the truck at a home in Tracy and arrested 18-year-old Angel Nietokalandrely and a 16-year-old from Livermore on July 16, followed by 18-year-old Damien Henriquez and a 17-year-old from Livermore on July 18.
