PORT-OF-SPAIN, Trinidad-Sean Antoine, 28, was sentenced to 19 years worth of hard labor on Tobago, a southern Caribbean island, for stabbing to death Kitty Pepe, 14, of Keene, in 2005. Antoine will only serve roughly 14 years of the sentence, as a result of local law. Pepe had lived in Tobago with her mother whose work was focused on sea turtle conservation. Pepe's grandmother said Antoine had been a family friend who had known Pepe for about 10 years, insisting the two were not in a sexual relationship. Antoine said he repeatedly stabbed Pepe on July 1 after she taunted him. This explanation caused jurors to convict him of manslaughter, as opposed to the more serious charge of murder, to the obvious outrage of the Pepe family.
