 Meanwhile, the family of a teen who drowned after jumping off a cliff at Quarry Park and Nature Preserve in Waite Park, questioning why the boy drowned. Authorities say 17-year-old Emmanuel Seward Jr. of Brooklyn Center never resurfaced after plunging from a 10-foot cliff into the water. His body later recovered by a dive team in around 30 feet of water. Seward's family says this is the third drowning at Quarry Park in recent years, and they are calling for the area to be closed.
