Maine man's release from prison leads to quadruple murder confession.

A man named Joseph Eaton has been charged with four counts of murder after killing his parents and two friends in Bowdoin, Maine. He was later arrested after shooting at vehicles along Interstate 295, wounding three people. Police found multiple cartridge casings of varying calibers in his vehicle. Eaton had been released from prison four days before the shootings. A note found at the scene referenced molestation and wanting to be freed of pain. Eaton's motive is still unknown.
