Brad Delp's suicide notes have finally been released. The lead singer of the band Boston, who died from carbon-monoxide poisoning after sealing himself in a room with two charcoal grills last week, called himself "a lonely soul" in a letter clipped to his shirt. "I take complete and sole responsibility for my present situation," another note read. "I have lost my desire to live." Four additional letters were found in an office addressed to Delp's fiancee, his children, their mother and another couple whose identity was not disclosed. Brad Delp was found dead on March 9.
