Teen tells how killer shouted ‘You must die’ as he stabbed mother to death while he watched on video chat

A Massachusetts teenager who witnessed the murder of his friend's mother on an iPad during an online chat took the stand against the woman's alleged killer Friday and told the court how heard 39-year-old Chris Piantedosi tell the victim 'you've got to die' as he repeatedly stabbed her with a knife. Authorities say Piantedosi fatally stabbed his girlfriend and mother of his two children, Kristen Pulisciano, in May of 2012. One of the couple's 15-year-old daughter's friends, 16-year-old Michael Edwards, was chatting with the girl online when the murder took place, and he witnessed much of it. 'She was saying, ''No, Chris, stop, I love you,''' Edwards told the court of the stabbing.
