26-Year-Old Dad Killed Son, Friend in Pennsylvania Car Explosion: Cops

A deadly Pennsylvania explosion that killed three, including a 2-year-old boy, over the weekend has been ruled a murder-suicide, officials said Thursday. In a series of letters mailed to the Allentown Police Department before his death, 26-year-old Jacob Schmoyer indicated his intentions to purposefully detonate the homemade car bomb that killed him, his own young son, J.J., and 66-year-old David Hallman, whom police described as an acquaintance of Schmoyer's.
