The boy who was taken to a hospital in a critical condition after a water emergency in northeast Minnesota has died.
The St. Louis County Sheriff's Office has confirmed on Thursday that 14-year-old David Beck, of Superior, Wisconsin, died overnight.
His family said he'd passed from complications that arose from his rescue from the water on Tuesday evening.
"The family said they were extremely appreciative for all of the work and effort put in by those involved during this incident," the sheriff's department said.
Emergency responders had been sent to Little Grand Lake near Sampo Beach, northwest of Duluth, just before 8:20 p.m. Tuesday.
Beck had been under the water for "multiple minutes," with bystanders having removed him from the lake when first responders arrived.
CPR and lifesaving measures were carried out, before he was taken to a hospital, where he is in a critical condition.
It happened after Beck and two other boys were swimming out to a diving dock about 75 yards off shore, with Beck going underwater, prompting the other two to yell for help.
Beck was found about 12-15 feet underwater by bystanders who came from the beach and nearby boats.
"Swimmer inexperience is believed to be the cause of the incident," the St. Louis County Sheriff's Office said on Wednesday.
