PARIS, OCTOBER 4 - Michael Harpon, the clerk of the Paris police station who killed 4 policemen yesterday by stabbing them, had "had visions and hearing of the voices" the night before: his wife said it, questioned by investigators and still in state as reported by the France Info radio station. The woman said her husband had uttered "confused" phrases. Various testimonies from colleagues speak of a person who often "was not taken seriously" in the workplace.
