Officers in Graham, Washington found the bodies of a father and his two children on Sunday, after the man apparently set his own home ablaze.

According to CBS News, Josh Powell set his home ablaze with his two sons, seven-year-old Charles and five-year-old Braden, trapped with him. Powell's wife, Susan, has been missing since 2009, and Powell has denied any involvement with her disappearance.

Just 10 minutes before the incident, Josh Powell delivered an email to his lawyer that read, "I'm sorry, Goodbye."
