First Responders Got Disturbing Calls Before Murder Of 4 People In Groton

Documents have revealed a timeline of disturbing calls to first responders in the days before a 22-year-old was charged with fatally beating his mother, grandparents and their caretaker with a baseball bat.

The Boston Globe reports the mother of Orion Krause called 911 Sept. 7 worried that he was suicidal after he abruptly left the home.

Documents sent to The Portland Press Herald show a woman called police around 5 p.m. the next day to report a call her husband had gotten from Krause, a former student of his at Oberlin College. The woman says Krause told her husband, "I think I have to kill my mom."

Police discovered the bodies of the four people that evening.

Krause has pleaded not guilty in the killings.
