‘Bullied’ Texas gunman hinted of attack online | How school shooting unfolded

19 school children were among the 21 shot dead by a gunman in Texas, making it the second deadliest mass school shooting in U.S. history. But how did it all unfold? Reports suggest that the 18-year-old gunman, Salvador Ramos, who was shot dead later, was bullied when he was in school. He had even dropped hints about the attack on social media. State Senator Roland Gutierrez said that the gunman's social media was full of photos of guns that he bought on his 18th birthday. Ramos first shot his grandmother, then left for the elementary school. He crashed his car outside and ran towards the building. Wearing an armoured vest, Ramos opened fire at the kids holed up in one room. He was then shot dead by a border patrol agent who managed to enter the school premises when the shooting was on.
