Police said the death of Barry K. Stewart occurred after he was located by troopers in Franklin County on Route 11B near Doug Smith Road.

Stewart, 55, allegedly shot two people to death Wednesday afternoon inside BridgeView Real Estate Services, 145 Clinton St., Suite 111, Watertown, where Stewart was formerly a real estate agent.

Shortly after 9 p.m. Wednesday, state police identified the two victims of Wednesday’s shooting as Maxine M. Quigg, 50, of Wellesley Island, and Terence M. O’Brien, 53, of Black River. The victims co-owned Bridgeview Real Estate Services, where the shooting occurred.

Following a be-on-the-lookout alert issued by state police, a state police K9 unit observed Stewart’s vehicle on Route 11B in the town of Dickinson, Franklin County, and attempted to pull the vehicle over. Stewart, according to state police, drove off the roadway and was found inside the vehicle with a self-inflicted gunshot wound.

He was pronounced dead at a nearby hospital.

Stewart, according to his business website, owned Homes by Barry Stewart, a franchise of eXp Realty. Stewart, according to his biography on the website, served in the Army for 25 years, and he moved to the North Country after retiring from the military.

“I don’t compromise my integrity for anything,” Stewart said in a video on his website called “A Little About Me.” “I figure if I have made it this far in life from where I came from that there is nothing anyone can do to me that I can’t recover from.”

The two real estate brokers shot and killed at their workplace were active in the community and known to always look out for their agents.

“The real estate community is absolutely turned over backwards,” said Linda J. Fields, a local real estate educator who taught the two.

Quigg and O’Brien, 53 worked together previously at Exit More Real Estate, and when they learned the business was closing, they decided to open their own brokerage, Bridgeview Real Estate Services LLC, in 2016.

Many of their former co-workers at Exit More joined them. They built a staff of somewhere between 35 and 40 agents. Fields said they weren’t just successful at their job, but they were kind people who were active in the community and had wonderful families.

“They were just the ideal brokers to work for,” Fields said. “They were absolutely wonderful.”

Fields also taught Stewart his real estate courses. She remembers him as nice, opinionated and a good Realtor. It appears Stewart left Bridgeview in March and had been working at eXp Realty in Watertown.

“As a student, he was very inquisitive,” she said. “He knew what he wanted to do. He was eventually going to open up a company.”

Fields said there had to be something awry with Stewart for him to commit such an act.

“It’s a sad situation all the way around,” she said. “Nobody should have passed away like that.”
