WRENTHAM -- The Wrentham Police Chief is applauding two "smaht" 12-year-olds for doing the right thing when they found a potentially dangerous object while on a walk Wednesday. The boys alerted adults when they found a hand grenade. According to Chief Bill McGrath, Kevin Castaneda and Alan Jackson, both 12, were outside exploring when they found a pile of debris as they were hiking. Exploring the pile of trash, the two boys found a hand grenade.According to McGrath, "Kevin and his friend Alan DID NOT give in to 'kid curiosity.'" Instead, the boys took a picture of the grenade, noted their location and headed home to tell an adult, who called 911. Wrentham Police and Fire and the Bomb Squad responded to the scene."Yes, the grenade was 100% real," McGrath said. "Luckily, it had been hollowed out and therefore harmless, but the boys had no way to know that when they found it."
