Authorities provided inconsistent and shifting information about what happened and how they responded in the days and hours following Tuesday's fatal shooting at Robb Elementary School, Uvalde, Texas.
While the investigation into the massacre is ongoing and much more is known about the two-hour period between the time Salvador Ramos killed his grandmother and the time police radio traffic indicated that the gunman, aged 18, was dead and that the siege was over, there is still much to be learned.
According to Steve McCraw, Texas Public Safety Director, Ramos shot his grandmother in the head sometime after 11 a.m. Gilbert Gallegos (82), who lives across from Ramos' grandmother and heard the shot while he was in his backyard, reported that he heard it. He sprints to the front, seeing Ramos drive away in a pickup truck. Ramos' grandmother comes towards him, pleading for help. He was covered in blood and she said, "Berto, that is what he did." Gallegos claims that he shot me. His wife called the police to report the shooting.
McCraw stated that 11:27 AM was the time McCraw captured a teacher prying open an exterior school door.
McCraw stated that the teacher leaves at 11:28 to retrieve a cell phone, and then returns through an open exit door. It is not clear why the teacher was attempting to retrieve a phone. Travis Considine, spokesperson for the Department of Public Safety, stated Thursday that investigators have not determined why the door was propped open.
McCraw stated that Ramos crashed the pickup into a drainage ditch near the school at 11:28 AM. Two men from a nearby funeral home heard the crash and ran to investigate. Ramos, a man with an AR-15-style rifle, and a bag containing ammunition, appears to be rushing out from the passenger side. Ramos shoots at the men but doesn't strike them. Both men make it to the funeral home, but one of them falls. The panicked teacher calls 911 after he emerges from school.
McCraw stated that 911 received a call at 11:30 AM reporting that there had been a crash and that there was a man carrying a gun at school.
McCraw stated that Ramos starts shooting at the school starting at 11:31 AM. As police cars arrive at the funeral home McCraw said. Ramos then moves around the school building.
McCraw stated Friday that the school district officer who was on duty that day wasn’t present at campus. This contradicts previous reports. After receiving the 911 call, the officer drove to the school and approached the man at the back who he believed was the gunman. McCraw stated that the officer "accelerated" towards the man who turned out be a teacher and "drove right past the suspect who was hunkered behind" a vehicle.
