Loris' granddad questioned

(ANSA) - Ragusa, March 1 - The paternal grandfather of murdered eight-year-old Loris Stival will be questioned by prosecutors on Thursday, sources said Tuesday.
    Andrea Stival was placed under investigation as an accessory to the murder and concealment of the body in February.
    Prosecutors said proceedings against Andrea Stival are a matter of course after the boy's mother Veronica Panarello, currently the only defendant in the murder, told a psychologist Loris was killed by her father-in-law and that they were lovers.
    Panarello has alleged Andrea Stival feared his grandson might reveal the affair.
    The man has denied both his daughter-in-law's claims.
    Panarello, 27, is on trial for premeditated murder and concealing a corpse in connection with the death of Loris at his home in the Sicilian town of Santa Croce Camerina on November 29, 2014.
    Prosecution documents seen by ANSA at the time of her arrest the following December alleged she killed the boy "via strangulation with a plastic cable tie", and named cruelty as an aggravating circumstance.
    Panarello later told investigators her son died by accident while playing with a plastic cable tie and that she threw his body in a ravine in a moment of panic.
