(CBS/WBZ/AP) SOUTH BERWICK, Maine - A boy found dead in Maine on Saturday has been identified as 6-year-old Camden Pierce Hughes of Texas. Authorities have arrested his mother, Juli McCrery for his murder.
Sources told CBS station WBZ that McCrery has confessed to giving her son an overdose of cough syrup that resulted in his death.
WBZ was first to break the news Wednesday afternoon.
McCrery of Irving, Texas, is in Massachusetts State Police custody in Concord and has confessed to killing her son, sources tell WBZ.
Camden Pierce Hughes's body was discovered in South Berwick, Maine over the weekend, wrapped in a blanket next to a dirt road.
"We were together for two years, but I've known (the boy) since the day he was born," said Robert Miller, McCrery's ex-boyfriend who also lives in Irving, Texas to WBZ. "He was a very nice boy. He was an innocent boy."
The break in the case came late Wednesday morning, when a Massachusetts state trooper spotted a blue Toyota Tacoma pickup truck at a Chelmsford rest area off I-495. The truck matched the description of a vehicle witnesses spotted at the Maine crime scene on Saturday.
Sources told WBZ NewsRadio that the driver of that truck, a woman in her 40s, was taken into protective custody after making statements regarding the death of her son. That woman has since been identified as Mccrery.
The truck, which had Navy insignia on the license plate, was taken to the State Police barracks in Danvers for processing.
After several hours of questioning, Procopio said state police decided to have the McCrery taken to a hospital for a medical evaluation. "It was not a critical medical emergency," he said.
The pickup towed from the rest stop is registered to McCrery, of Irving, Texas.
However, police declined say whether the woman made any incriminating statements during questioning and what transpired during the encounter with police at the rest stop.
Investigators have fielded more than 200 tips since the boy's body was found. Police also conducted DNA tests on the body, released a detailed photo of the boy's sneakers and notified Interpol.
For days police have been seeking the public's help to identify the boy. They released a computer generated photo of a blond-haired, blue-eyed boy wearing a gray camouflage hoodie.
Autopsy results on Camden's body have not been released.
