Texas police have walked back on their claim that a school teacher left a door of Robb Elementary School ajar, which 18-year-old Salvador Ramos used to get inside and kill 19 students and two teachers on 24 May.
The change in stance came after her lawyer said on Sunday that though the teacher initially propped the door open to get food from a car, she closed it shut after realising that the heavily-armed gunman was heading towards the school.
