Stacy Pagli was sentenced in Westchester County Court Tuesday on her guilty plea to first-degree manslaughter.
The 38-year-old Pagli was originally charged with murder. The plea deal was offered after doctors for both sides agreed she was emotionally disturbed when she killed Marissa Pagli at Manhattanville College in Purchase.
Marissa Pagli, a freshman at the school, was found dead in February 2010 in the family's on-campus apartment. Her father, a maintenance supervisor at the college, found the body.
Stacy Pagli told police she had killed her daughter because she "pushed my last button" and was disrespectful.
After the murder, Stacy Palgi tried to kill herself by first cutting her left wrist and then by hanging herself on a doorknob.
