>William Brown had errands to run on a chilly Texas evening, and his grandmother was happy to lend him her light-blue Lincoln Town Car.
>Brown stopped at a store selling vaporizer smoking pens outside Fort Worth on Jan. 27. He sat alone in the parked car, put his lips to a pen, and soon after, an explosion sent shards of metal into his face and neck, said Alice Brown, his grandmother.
>He thrashed and fell out of the car, trying to regain his balance on the hood and trunk before collapsing, she said, according to evidence from the scene conveyed to her by authorities.
>Brown, 24, held on for two days before he died at a hospital. The cause of death was listed as stroke after the carotid artery in his neck was severed by “penetrating trauma from exploding vaporizer pen,” the Tarrant County medical examiner found.
>William was the third generation of electricians in the family, said his father, Steve Brown, and they worked side by side.
