 The family of a teen who drowned after jumping off a cliff at Quarry Park Nature Preserve in Waite Park is 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, and his body was later recovered by a diving team in around 30 feet of water. Seward's family says this is the third drowning at Quarry Park in recent years and are calling for the area to be closed.
