Teen witnesses murder of Mass. mom on iPad camera, prosecutor says

(CBS/AP) WOBURN, Mass. - A prosecutor says the fatal stabbing of a Massachusetts woman was witnessed by a friend of the woman's teenage daughter who had been video chatting with the girl on an iPad.

The details were released in Woburn District Court on Monday as Christopher Piantedosi was arraigned on a murder charge in the death of Kristen Pullisciano.

A prosecutor said Piantedosi chased Pullisciano into their daughter's bedroom and stabbed her 34 times Thursday in Burlington. The person the daughter had been video chatting with saw and heard parts of the attack.

Authorities say the couple had a longtime relationship but were not living together at the time.

According to CBS Boston, the prosecutor says during the attack the teen's friend heard Pulisciano pleading, "Chris, please stop, I love you," and Piantedosi saying, "You're going to die."

Their teenage daughter called 911.

It was also revealed in court Monday that Piantedosi attempted suicide earlier in the week but was hospitalized and then released the day before the attack, CBS Boston reports.

Piantedosi was ordered held without bail. He is due back in court June 7 for a probable cause hearing.

According to the Union Leader, Piantedosi is the man who police previously nicknamed the 'remorseful robber' after he admitted to stealing a woman's wallet and GPS in New Hampshire. Police say days after the robbery, he knocked on the 61-year-old woman's door to return $90 and the GPS, along with an apology letter he signed "stupid." He later turned himself in.
