Investigators remain at the scene of a helicopter crash that killed two people along the Quebec-New Brunswick border on Sunday.

The crash happened around 4:00pm when a Bell 206 helicopter hit powerlines then smashed into an embankment before coming to a stop in the Restigouche River.

The Transportation Safety Board assessed the scene Tuesday outside Campbellton, N.B. trying to figure out what went wrong.

“Today what we focused on was to move the wreckage out of the river,” says TSB Regional Investigator Daphne Boothe. “We've been doing that all day, it's a lengthy process, at this time they have moved most of the wreckage off of the river, and it's going to be moved to a secure location.”

The crash killed former hockey player-turned singer Bob Bissonette, and pilot Frederick Decoste.

A third man, Michel Laplante, was pulled from the wreckage and taken to hospital in nearby Campbellton, where he is expected to recover.

“Thank God there were people there on the scene that ran to the water and went right to the helicopter and walked the gentleman out. I’m sure, dazed like he was, he probably wouldn’t of made it by himself,” says area resident Ian Comeau.

Residents of Flatlands, N.B. say they are shaken by the incident.

“It will always be there for me, unfortunately,” says Patti Gaille who watched the scene unfold from her backyard. “As soon as I got outside and looked downriver, the helicopter had hit the line and just plummeted into the river. The water went everywhere and then parts flew off everywhere, and they were just floating away.”

Residents also say it could have been much worse, as the river where the helicopter crashed is usually very busy.

“On a hot summer days there’s hundreds of troopers that go by here, kayakers, paddleboards,” says Gaille.

The Transportation Safety Board says it's too early to tell exactly what caused the helicopter to go down, and couldn't give a timeline for the remainder of its investigation.

With the wreckage now moved to a secure location, residents of the community say they are ready to try to move on.
