The juvenile suspect had previously been at the register inside the store, but had to go outside to get more money.Mills, 16-year-old and two others then came back inside the store and went to the register.That's when the 16-year-old and Mills pulled out guns and began to open fire, according to surveillance video viewed by investigators.While Cohen was on the ground Mills stood over him, shooting Cohen multiple times, according to the affidavit.
The 16-year-old, who is not being identified because of his age, was transferred to a Dallas hospital.Mills had previously been arrested for unlawful carrying of a weapon in June 2022, in which he posted a $500 bond, according to the Dallas County Sheriff's Office. In December, MIlls' case was dismissed after he agreed to forfeit three firearms, according to court documents.Police say they believe Cohen knew both Mills and the juvenile suspect.
