Twisted school shooter Salvador Ramos scooped up a handful of his child victims' blood and smeared it on a whiteboard before writing 'LOL', it has been revealed.
Evil gunman Ramos, 18, massacred 19 innocent children in a sickening rampage at Robb Elementary School in Texas, after first shooting his own grandmother at a house in May last year.
By the end of the horrific spree in the city of Uvalde, Ramos had killed 19 kids and two teachers before being gunned down by police.
