 The family of a 17-year-old Brooklyn park boy who died after jumping from a 10-foot-high cliff into a quarry near St. Cloud now says they want a private investigation into his death and an autopsy, saying they want clarity and accountability. Emmanuel Seward's death was ruled an accidental drowning after he jumped from the cliff at Quarry Park and Nature Preserve near Waite Park and never surfaced. He was found in more than 30 feet of water.
