(PORT HURON) -- A Yale woman convicted of plotting a fatal stabbing attack on her father has again been sentenced to life in prison. Tia Skinner was given a no-parole sentence in 2011 when, at 17 years old, she was convicted of first-degree murder in St. Clair County. But she had another day in court Thursday after the U.S. Supreme Court struck down mandatory no-parole punishments for teenagers. Judge Daniel Kelly issued the same sentence for Skinner, who is now 20, calling her "the architect" of the plan to attack her parents. Tia's boyfriend at the time Jonathan Kurtz and his friend James Preston attacked and killed Skinner's father, Paul Skinner, in their Yale home in November 2010. Her mother, Mara Skinner, was seriously wounded after being stabbed more than 25 times. Kurtz and Preston, who were 18 at the time of the crime, were sentenced to life in prison without parole. The former honors student said Thursday in court that she loves her family and acknowledges she could have stopped the attack.
