Twisted Sean Duffy, 25, targeted Facebook tribute pages and even posted videos on YouTube taunting the dead and their families. Among his victims was 15-year-old Natasha MacBryde, whose body was found on Valentine's Day after a train hit her near her home in Bromsgrove, Worcs. In a practice known as trolling, Duffy posted vile comments including "I fell asleep on the track lolz" on the Facebook tribute page created by her brother James, 17. Five days after her death he created a YouTube video called Tasha the Tank Engine, with her face etched on to the front of the famous train.
