The teenage daughter of a Shrewsbury woman beaten to death by her husband said her mother ‘‘lived in hell’’ so she could provide her children a stable home. Kayla Rosiello, 16, issued a victim impact statement at the sentencing in Worcester Superior Court on Tuesday of her father, Keith Rosiello. Keith Rosiello was sentenced to the mandatory sentence of life in prison without parole in the February 2010 killing of Maureen Rosiello in front of their two children. He was convicted last week of first-degree murder. The Telegram & Gazette reported that the girl said that despite counseling, there are times when she struggles to find the strength she needs to go on. At such times, she said, she thinks about what her mother would have wanted for her.
