More than a week after 18-year-old Salvador Ramos killed 19 students and two teachers inside their fourth-grade Texas classroom, investigators are still searching for a motive. Texas Rangers have seized a black iPhone 13 Pro-Max found with Ramos’ body inside Robb Elementary School and have obtained a warrant for all data on the phone, “including digital images, text messages, address books, photos, video, voice messages and any GPS or remote tracking system information,” according to the paperwork obtained by KHOU. The search warrant also describes how two male witnesses spotted a man with long hair and dressed all in black get out of a crashed Ford and load a rifle with a magazine on May 24.
