Deputy on administrative leave

Kelly Rosenstrach

HUDSON — Columbia County Sheriff’s Deputy Kelly Rosenstrach was placed on administrative leave Thursday as more information is coming to light about an alleged assault that took place July 5 at the Kinderhook home she shares with ClubLife Health and Fitness owner Alex Rosenstrach, according to the sheriff’s office.

“At this point in the investigation, it has been determined that no other deputy sheriffs were at this residence at the time of the incident,” according to a press release from the sheriff’s office.

The investigation into the alleged assault is being headed up by the sheriff’s office and assisted by the state police Special Investigative Unit, according to the sheriff’s office.

The lead investigative agency is determined by the agency assigned to the case by Columbia County 911, sheriff’s office Public Information Officer Lt. Louis Bray added.

The sheriff’s office defended its investigation of a case that may involve one of its employees.

“We investigate every incident with the same integrity and skill,” Bray said.

Sheriff David Bartlett requested assistance from state police in the early stages of the investigation, Bartlett said.

“Our investigators, and investigators from the New York State Police Special Investigative Unit have worked side by side throughout this entire incident, along with the Columbia County District Attorney’s Office,” Bartlett said in a statement. “At the conclusion of this investigation, anyone, including a member of my agency, who participated in this assault will be held accountable.”

State police would not comment on the investigation and deferred all questions to the sheriff’s office.

“The Special Investigations Unit was assigned to the assault case in Kinderhook after the Columbia County Sheriff’s Office requested state police assistance,” said Beau Duffy, state police director of public information, in a statement. “The SIU is part of the state police Bureau of Criminal Investigation, and is assigned to investigations based on the nature of the case.”

The investigation stems from an alleged assault at the Rosenstrach home on county Route 21 in Kinderhook. Valatie Rescue Squad was called to Rosenstrach’s residence at 1:10 a.m. July 5, said Robert Lopez, director of Columbia County 911.

Minutes later, Sheriff’s deputies arrived on the scene to assist the Valatie Rescue Squad, according to the sheriff’s office.

“Deputies arrived on scene and found a male who had been the victim of an assault that had taken place during a gathering at this location,” according to the sheriff’s office.

The Valatie Rescue Squad was on the scene for 44 minutes before transporting the victim by ambulance to Albany Medical Center, Lopez said.

“An investigation by members of the Columbia County Sheriff’s Office is currently underway to determine the circumstances surrounding this incident,” according the sheriff’s office.

Police executed a search warrant at the Rosenstrach home Tuesday afternoon to secure evidence related to the assault investigation, the Sheriff’s Office said.

Sheriff’s office investigators are following all leads and conducting a thorough investigation, Bray said Thursday.

The search warrant was signed by Columbia County Judge Richard Koweek. Executed search warrants are not public record until after an arrest is made, according to Lucian Chalfen, director of public information for the Office of Court Administration.

The sheriff’s office is asking anyone with direct knowledge of the alleged assault to contact Investigator Ian Boehme at 518-697-0191.

Boehme was promoted to the role of investigator in 2018 after serving as school resource deputy in the Chatham Central School District. When he was promoted, Kelly replaced him as the district’s school resource deputy, according to the Chatham School District website.

Kelly served as Chatham’s school resource deputy until April, according to Salvatore DeAngelo, the district’s superintendent. She was previously known as Kelly Briscoe, but she took the name Rosenstrach after her marriage, DeAngelo said.

Kelly has been a member of the Columbia County Sheriff’s Office for nearly eight years, joining Sept. 26, 2012, according to county records. She earned $68,046 in 2019, according to state records made public by the Empire Center.
