LATEST: Boston frontman BRAD DELP described himself as a "lonely soul" in a suicide note he wrote before killing himself last Friday (09MAR07). The MORE THAN A FEELING singer, 55, was found dead in his New Hampshire home by his fiancee PAMELA SULLIVAN. He had been suffering from depression. Toxicology tests show Delp had committed suicide by carbon monoxide poisoning. Police located his body on the bathroom floor with his head on a pillow - he had blocked himself in with two charcoal grills. Paper-clipped to his shirt collar as the suicide note. It read: "Mr. Brad Delp. J'ai une ame solitaire. I am a lonely soul." In another note taped to a garage door leading into the house, he wrote: "To whoever finds this I have hopefully committed suicide. Plan B was to asphyxiate myself in my car." Delp also left another note at the top of the stairs warning of the carbon monoxide fumes. It added, "I take complete and sole responsibility for my present situation. I have lost my desire to live." Cops also discovered letters addressed to Sullivan, his children and their mother MICKI DELP and another couple whose identity is currently unknown.
