Eric Morelli, the 19-year-old man who killed his friend's sister, Kristen Milano, also 19 — after throwing a lit firework which landed in her bedroom window and ultimately killed her last June — has now been sentenced to prison.

Kristen's family begged for Eric to get the maximum sentence during the court hearing — he ended up getting 15 years in prison, and will be suspended after he serves seven years. He will spend five years after that on probation, and will be required to come up with a $1,000 charitable donation for every year of his probation.

According to reports, Eric was throwing lit fireworks at Jason Milano's (Kristen's brother) bedroom window, as the two allegedly had plans to smoke weed — the first two bounced off, but the third one landed in the house. Kristen later died from inhaling an overwhelming amount of smoke.

“Kristen Milano was one of my friends. She was a great friend. I think about her every day and I can't believe I caused her death,” Eric said.

His attorney Raymond Hassett backed him up, stating, “Eric never intended to harm anyone that night. He is deeply sorry for his spontaneous and impulsive act which has now caused so much pain.”
