MILTON (CBS) — As hunters head into Blue Hills Reservation for the first time since 1893, the Norfolk District Attorney’s Office is asking them to be on the lookout for the remains of a man missing since 2014 and presumed dead.

James “Jamie” Robertson of Avon disappeared New Year’s Day 2014, when he was kidnapped from his home. A poster distributed to hunters gathering at Blue Hills Reservation Monday morning stated that the Norfolk DA’s office believes he was the victim of foul play, but his body has not been found.

“We do not know that Jamie Robertson is in the Blue Hills,” Norfolk DA Michael W. Morrissey said. “Our information is that he may be found in a wooded area. We know he was taken from Avon, and believe at some point he was then in Canton.”

Robertson’s mysterious disappearance is still under investigation. He was last seen getting into a silver Toyota Camry around 12:50 p.m. on January 1, 2014 with two men claiming to be constables.

Robertson’s parents are pleading for answers. Jamie was the second of Ginny and Dave Robertson’s four boys.

“Jamie was awesome,” Ginny said.

“The last memory I have of Jamie is him going up the street in the back of this car,” Dave Robertson said.

The two men had handguns and badges, and claimed they were taking Robertson, who was on probation at the time, for a random probation-related drug test. Robertson’s family learned the next day that the probation department had not sent anyone to the house.

“I don’t know why I said it, but the first thing that came out of my mouth was, ‘how do you know they’re constables?’” Dave said.

“He says, ‘oh, dad, they have badges, they have guns, they have all the official paperwork with my picture on it,’” Ginny recalled.

Scott Morrison, 46, of Norfolk and Alfred Ricci, 45, of Canton were arrested in May 2014 and charged with kidnapping Robertson. Three months later, Dedham Police Officer Michael Schoener, 40, was arrested for allegedly supplying the badge, holster, and handcuffs used in the kidnapping. Prosecutors said Schoener gave the items to James Feeny, a man he allegedly bought pills from, before they were used by Morrison and Ricci.

The Norfolk DA’s office believes Robertson’s body may be in a wooded area.

“We don’t confine this request to this area,” said Morrissey. “We think hunters across Massachusetts can be an outstanding resource in circumstances like this. Though a hunter would naturally report seeing human remains, they might not think to report seeing a red or maroon sweatshirt, or stop at the sight of a pair of jeans. We are asking for the hunting community’s help.”

Robertson was last seen wearing a red or maroon sweatshirt, black shirt, blue jeans, and brown shoes. Anyone who sees anything resembling human remains or clothing worn by Robertson should contact the Mass. State Police assigned to the Norfolk DA’s office at 781-830-4800.

“I think they’re doing the best they can,” Ginny Robertson said. “I think they’re determined to bring our son home to us.”
