Man kills elderly mother

(ANSA) - Bologna, November 9 - A man was arrested in Bologna Friday on suspicion of murdering his elderly mother.
    The woman was initially thought to have died a natural death.
    The man confessed to strangling his mother, 85-year-old Elvira Marchioni, in a fit of rage and then staging the scene to look like she had died of natural causes.
    The 58-year-old draughtsman, Bruno Grandi, was her only son.
    "I couldn't take it any more," he reportedly told police, saying he had been "worn out" by caring for her.
