A Pennsylvania mother, Trinh T. Nguyen, pleaded guilty to killing her two sons and attempting to murder a neighbor. She shot her 9-year-old and 13-year-old sons in the head while they were asleep, and they later died after being taken off life support. Nguyen was sentenced to two life sentences without parole for the murders and a maximum sentence of 10 to 20 years for attempted murder. The plea and sentence ensure that she will spend the rest of her life in prison. Nguyen had planned the murders in advance and left a handwritten will.
