On May 12, 2007, Alec Kreider, a 16-year-old high school student at the time, murdered his classmate and friend Kevin Haines, his father Thomas Haines, and mother Lisa Haines by stabbing them to death in their home in Manheim Township, Pennsylvania, United States. Kreider was arrested a month later on June 16 and charged with three counts of first degree murder. He pleaded guilty to all charges, and was subsequently sentenced to three consecutive life sentences without the possibility of parole. Kreider later became eligible for a re-sentencing hearing following the United States Supreme Court's 2012 decision in Miller v. Alabama, which held that mandatory sentences of life without the possibility of parole are unconstitutional for juvenile offenders.
