TROY — City police are investigating the killing of a 21-year-old Schodack woman they said was the victim of an "extreme act of violence" inside a home on Pawling Avenue.

The victim, identified as Brianna Haughton, was found dead at the scene when police arrived about 5:30 p.m. on Sunday, Troy Police Chief Brian Owens told reporters Monday.

The chief said police have identified a "person of interest" who was being treated at a local hospital with significant wounds and is in stable condition.

"It is fair to say that there is a connection, a relationship," Owens said. "It does not appear to be a stranger at this point."

Police went to 491 Pawling Ave. at 5:30 p.m. Sunday after someone called to ask that officers check on a child's welfare. They found Haughton at the home. Police found the child — an infant who is related to Haughton — safe in another location.

"It was certainly an extreme act of violence. I don't know what preceded it and it's too early to say," Owens said. "But clearly it was an extreme act of violence for sure."

Police remained at the home on Monday. Evidence technician remained outside the house, as did police tape. The location, near the corner of Pawling Avenue and Blakley Court, a short walk from Sacred Heart School.

"It's a residential area which is intermixed with businesses. There's also a school nearby. I don't know how I'd classify it in terms of crime level," Owens said when asked about the neighborhood's crime activity. "A homicide that occurs anywhere in the city is very concerning."

Troy had one homicide in 2018.

"Violence that occurs anytime in the city is difficult to deal with ... it's the start of the year but for us it seems like the years and days and weeks all run together," said Owens, who has been with the Troy police department more than 21 years. Mayor Patrick Madden appointed Owens police chief in November 2017.

"In terms of statistics, I realize that's important because it's classified by the calendar year but it's just unfortunate that we have violence of any type in the city," Owens said. "And it is difficult and it seems I guess, in a sense, the city of Troy has been fortunate that we haven't had as much violent crime as other communities. But anytime it happens it's very heartbreaking."
