A 6-year-old boy died Monday after being pulled from the water at Sandy Point State Park in Annapolis, authorities said.

Saquan L. Kennedy of Baltimore was at the park, which sits on the northwestern shore of the Chesapeake Bay, with friends and family on Monday morning when he and some other children went playing out in the water, in an area without lifeguards. Kennedy went under, and the children alerted the adults, who called for help, said Sgt. Art Windemuth, a spokesman for the Maryland Department of Natural Resources Police.

The beach was crowded with about 1,000 people, and other beachgoers formed a chain to look for Kennedy in the area where he disappeared. By the time the Anne Arundel County Fire Department arrived, around 8 a.m., Kennedy had already been pulled out of the water and was receiving CPR, said fire department spokesman Capt. James Rostek.

“It’s a well-protected, safe area to swim, but with water anything can happen,” Rostek said. “It was a very tragic way to start the holiday.”

Kennedy had a faint pulse as emergency personnel took him to Anne Arundel Medical Center, where he was pronounced dead, Windemuth said.
