XIV. Luis, a PNP officer, was off duty and resting at home when he heard a scuffle outside his house. He saw two of his neighbors fighting and he rushed out to pacify them. One of the neighbors shot Luis by mistake, which resulted in Luis's death. Marian, Luis's widow, filed a claim with the GSIS seeking death benefits. The GSIS denied the claim on the ground that the death of Luis was not service-related as he was off duty when the incident happened. Is the GSIS correct? (3%)
