BOISE, Idaho (AP) — A 22-year-old Idaho man will spend the rest of his life prison for killing a former Arizona power company executive, his wife and their adult son at a Boise home.

Adam Dees of Nampa was handed three life sentences on Friday with no chance for parole. Dees pleaded guilty in June to killing 80-year-old Theodore M. Welp, 77-year-old Delores Elaine Welp, and 52-year-old Thomas P. Welp on March 8 or 9. The bodies were found March 10.

They were each shot in the head and struck repeatedly with a baseball bat. During Friday's hearing, a teary-eyed Dees told the court that he was sorry, while also mentioning that he had decided to live crazy right before killing the Welps.
