Police received information from the public on Thursday morning of a potential significant weapons-related threat. The information suggested a 19-year-old Halifax-area man and a 23-year old woman from Geneva, Ill., had access to firearms, Brennan said.
“We received a threat that individuals were planning on targeting a public venue in Halifax, to go there and commit mass killings of civilians and to ultimately kill themselves,” Brennan, the senior Mountie in the province, said in a phone interview Friday night.
Brennan would not say which venue was being targeted.
Brennan said firearms have been seized, although he could not say what kind, how many, or where the weapons were seized.
“The weapons seized had the ability to inflict a lot of casualties if used in a populated area,” said Brennan.
Police say they found the 19-year-old man dead at a home in the Halifax-area around 1:20 a.m. Friday.
Brennan would not elaborate on the circumstances surrounding his death, saying the issue has been referred to the province’s Serious Incident Response Team, which reviews all serious incidents involving police in the province.
A statement from the Serious Incident Response Team, known as SiRT, said police found the man dead when they entered the residence.
“(These) people were of the same destructive mindset,” he said, although he would not elaborate on the nature of their mindset.
Brennan said he’s “extremely confident” that all participants in the incident have been arrested.
“We’re very, very confident that we got all those that we needed to get,” he said. “There is no further threat . . . to the general public.”
Nova Scotia Premier Stephen McNeil also praised police.
“On behalf of all Nova Scotians, I thank our police officials, here and in the United States, for their quick and professional work. We are grateful for their dedication and vigilance,” he said in the statement.
