The identities of four of the six people who died in Minnesota waters over the past few days have been released by authorities.

On Monday, the Hennepin County medical examiner's office identified a man who drowned Saturday night at the Elm Creek Park Reserve beach in Maple Grove as Vishwanathan Shankar, 30, of Rockville, Md.

And the woman whose body fishermen found floating near the Crystal Lake boat landing in Burnsville early Sunday was identified as that of Jocelyn Renee Brengman, 24. Foul play is not suspected, but the circumstances surrounding Brengman's death are under investigation, according to Dakota County Sheriff Dave Bellows.

The man whose body was recovered about 6:25 p.m. Sunday from the St. Croix River after he jumped off a cliff and drowned was Nicholas Paul Johns, 26, according to the Chisago County Sheriff's Office. His city of residence was not released.

Meanwhile, the search continued for a man who apparently drowned in the Lower Lake North part of Lake Minnetonka on Saturday night, according to Hennepin County Sheriff's Office spokeswoman Lisa Kiava. The name of the man, a Twin Cities resident in his 40s, has not been released.

In yet another fatality on Minnesota waters, the body of a 26-year-old man from St. Louis Park was recovered Sunday from Lower Whitefish Lake, near Brainerd. He jumped off a pontoon boat late Saturday but did not resurface.

The unidentified man's body was recovered in about 90 feet of water at midmorning Sunday and taken to the Ramsey County medical examiner's office.

And at about 5 p.m. Friday, Clayton Olaf Deraas, 16, of Duluth, died after hitting his head on a boat and slipping underwater on Island Lake in St. Louis County. The Sheriff's Office said Clayton Olaf Deraas was swinging from a rope when he hit his head on a nearby boat.

Numerous people tried to help him but he went underwater and wasn't immediately found. Rescue workers recovered his body about three hours later.
