Chilling video has emerged showing the suspected gunman who killed 17 people and wounded 17 more at a Florida high school in February bragging about his plans to carry out the massacre. ‘When you see me on the news you’ll know who I am,’ Nikolas Cruz says while laughing creepily in three separate clips recorded on his cell phone. ‘You’re all going to die. Pew pew pew. I can’t wait.’ The video clips were released by Florida prosecutors.
