On Sunday, the Massachusetts State Police said in a statement that a "body believed to be the missing 6-year-old boy" — identified by police as Mas DeChhat — was "located by a kayaker in the Merrimack River this morning." The Newburyport Fire Department, which also confirmed the recovery in a statement released Sunday afternoon, said that Mas "had been missing since he entered the water during his family's recreational visit to Deer Island on Thursday, June 12.""His mother, Boua DeChhat, 29, valiantly tried to save him and lost her life in doing so," they wrote. Prior to her death, Boua was able to save her 7-year-old daughter, who also attempted to help her brother. According to NBC Boston, the boy's body was found by Darin Kelsey, who told the outlet he "was out for a 30-minute kayak" when he came across the boy's body in the water, which is about a half mile downstream from Deer Island.

River to Rescue Kids, Search for Missing Son Turns to Recovery Operation "I went out and looked along the shores and looked under docks and I was on my way back in and saw something floating kind of in my path," explained Kelsey, who lives along the Merrimack River. "I was hoping it was a stick or a log, and as I got closer I realized it was the boy. He kind of floated right by me." Courtesy Newburyport Firefighter Michael Kent Tragedy struck on Thursday evening while the family of six from Lowell, Mass., was visiting Deer Island, "a recreational area accessible by road that juts into the Merrimack River in Amesbury, near the Newburyport line," state police said in a previous statement. Around 7 p.m., Boua's 31-year-old husband "returned to their car in the island's small parking lot to retrieve some gear," police said. Around the same time, Mas, who was on land at the water's edge, reached for a stick in the water, fell in and then "began to be pulled away by the swift current." Police say his sister fell into the water while trying to grab him. 15-Year-Old Texas Boy Dies After Slipping Into Bayou While Fishing With His Friend Boua, who "was not known to swim," entered the water to save them but also became swept up in the current, police said. After returning back from the car, the father entered the water in hopes of saving his three family members, but "was not a swimmer" and "began to struggle" in the water himself, according to police. He eventually exited the water and was later treated at Seabrook Hospital for exposure and hypothermia. Police say Boua and her daughter were carried west "under the Whittier Bridge" in Amesbury before a fishing boat operator allegedly saw the pair and pulled him onto the vessel. The NFD previously said Boua was "unresponsive" when she was pulled onto the boat. At the time Bou and her daughter were pulled from the water, "Mas DeChhat was not observed in the water," state police said in Saturday's statement.
