A second teenage boy has died as a result of Thursday's two-car collision in Antigonish County, and a man has been charged in the case.

William Fogarty, of Antigonish, has been charged with two counts of dangerous operation of a motor vehicle causing death. The 30-year-old man remains in RCMP custody and is scheduled to appear in Antigonish provincial court on Monday.

RCMP said 17-year-old Nicholas Landry of Tracadie died overnight at St. Martha's Regional Hospital. He was a passenger in a vehicle driven by 16-year-old Kory Mattie of Havre Boucher, who died in the crash.

The collision on Highway 4 in Tracadie was reported just after 3 p.m. on Thursday. RCMP said visibility was good and the road was clear at the time of the crash.

On Friday, flags at East Antigonish Education Centre — where Landry and Mattie were in high school — were at half-mast.

"They're very well-liked by the student body. They were active young men in our school and we're going to be saddened by them not being here," said Janice Gough, the principal of the school.

"Our high school student body is relatively small and it's like a family, so they're helping to support each other."

Herb Delorey, the warden of Antigonish County, lives just down the road from where the accident happened. He said when he arrived home on Thursday he could see the emergency vehicles.

"We certainly, right away, noticed the fact that there had been a very, very serious accident," he told CBC News on Friday.

Delorey said word spread quickly about the accident and its victims.

"It's a terrible, terrible tragedy when you see two young people from your community lose their life unnecessarily," he said.

"It certainly has a traumatic impact on the whole community."

RCMP Staff Sgt. Tony Perry said Fogarty was the driver of the second vehicle involved in the crash and was treated for minor injuries and released from hospital. He was taken into custody on Friday.

The investigation into the incident continues.
