Police operations continue at the site of the mass shooting in Plymouth in the southwest of England, as people lay flowers for the victims. No motive has emerged for the bloodshed at the hands of 22-year-old gunman Jake Davison, who killed himself after the six-minute spree. Davison's first victim was his 51-year-old mother, Maxine, at her house in a quiet residential area. Davison then shot and killed toddler Sophie Martyn and her father, Lee, 43, on the street outside, before taking the lives of another man and woman nearby, the police said. IMAGES
