On 23 June 1848, the mutilated body of John Hamp (hutkeeper for William Pinkerton) was found near his hut at Stoney Point. His hands, body and head were battered and a deep cut had been to the skull (over his left eye) by a sharp instrument. A saw was found inside the hut with hair, blood and brains on it. Dishes, pots and blankets had been taken from the hut. Tracks were found leading to the Lake, including the distinctive tracks of Mingalta. Mingalta and Malgalta were later arrested and charged with Hamp’s murder.
