The New Brunswick RCMP are conducting new searches this week in connection with the disappearance of Chris Metallic four years ago.

The 20-year-old Mount Allison University student was reported missing on Nov. 25, 2012 following a house party in Sackville, N.B.

Police say they found footwear belonging to Metallic off the Haute-Aboujagane Road a few days after he disappeared.

The RCMP have used police dogs and a helicopter to search in and around the Sackville and Haute-Aboujagane Road areas since his disappearance four years ago.

Const. Brian Venoit and his specially trained German shepherd named “Doc” have come from Nova Scotia to help look for clues.

“He can find buried remains, he can find something in the water,” said Venoit. “There's a lot of variables to what we do. Temperature, weather, length of time we've been doing it.”

The RCMP dog has been searching this area since Monday and will continue to do so at least until Friday. Doc is able to detect at least one of the 30 chemicals within the human body after death.

“It's four years old now so our general duty dogs can't locate something that's four years old. Science allows us to say that we can do that,” said Venoit.

Ground search and rescue teams also joined in the search, as well as the RCMP underwater dive team, who scoured the Tantramar River.

Police say they will be conducting new searches in the Sackville area this week as they continue to investigate Metallic’s disappearance. The area is about 16 kilometres from the house party Metallic attended in 2012.

"We continue to receive information about the disappearance of Chris Metallic," said Sackville RCMP Sgt. Paul Gagné. "By conducting these new searches we will be following up on some of that information in order to see if it provides any more information about what happened to Chris."

Police are asking the public to stay away from search areas so as not to disturb any possible evidence or disrupt the search.

Metallic is described as aboriginal, with short, dark black hair. He is six feet tall and weighed about 180 pounds at the time of his disappearance. He was last seen wearing a shiny, bright blue sweater and jeans.

Anyone with information about Metallic’s whereabouts or his disappearance is asked to contact the RCMP or Crime Stoppers
