Kristen Pulisciano Murder: iPad Video Chat Lets Teen Witness Murder

"He could hear the victim saying, "Please, please.' He could hear the daughter yelling, 'No. No.'"

Middlesex County, Mass. Assistant District attorney Nicole Allain made this assertion during the arraignment of "remorseful robber" Christopher Piantedosi, who is accused of murdering his ex-girlfriend, Kristen Pulisciano, by stabbing her 34 times.

Allain said the killing was witnessed by a friend of the couple's daughter who was in the middle of a video chat on an iPad, according to the Union Leader.

"He could hear the victim saying, 'Please, please.' He could hear the daughter yelling, 'No. No.' He then heard the defendant say, 'You gotta die. You gotta die.' He then heard the victim say, 'Chris, please stop. I love you' and then the defendant began stabbing Kristen numerous times,” Allain told the court.

Prosecutors claim Piantedosi kicked in his daughter's bedroom door and threw Pulisciano on the bed before stabbing her with a butcher knife, according to the Boston Globe.

"You are going to die," Piantedosi allegedly said, according to prosecutors.

Prosecutors claim Pulisciano died of a stab wound to the neck, according to MSNBC.

Piantedosi was previously known as the "Remorseful Robber" after he stole a woman's wallet and GPS device from her purse in 2011 and later returned the items, as the Union Leader previously reported.

Piantedosi was ordered held without bail until his next court appearance on June 7.
