DETROIT (AP) — Assisted suicide advocate Jack Kevorkian died in a Detroit area hospital following a short illness at the age of 83, according to a close friend and prominent attorney. Kevorkian died at 2:30 a.m. Friday after being hospitalized at William Beaumont Hospital in Royal Oak since last month with pneumonia and kidney problems, his attorney Mayer Morganroth said. An official cause of death had not been determined, but Morganroth said it likely will be pulmonary thrombosis.
