The homeless man who admitted to fatally stabbing a beloved Rockland County library security guard in 2020 has been found mentally incapacitated and will be committed to a state mental health facility instead of being sentenced this week.
Blanchard Glaudin, 31, was declared unable to understand the legal proceedings against him due to mental disease or defect, Rockland County District Attorney Thomas Walsh II announced Friday, Feb. 27.
Glaudin had previously pleaded guilty on Dec. 9, 2025, to second-degree murder in the Feb. 18, 2020, killing of Finkelstein Memorial Library security guard Sandra Wilson in Spring Valley, as Daily Voice previously reported.
As Daily Voice reported, Wilson, 52, was stabbed multiple times inside the Spring Valley library around 2 p.m. after she asked Glaudin to turn down loud music. She died from her injuries. Wilson was a mother of three and a new grandmother whose death shook the Rockland community.
At his plea, Glaudin admitted that he repeatedly stabbed Wilson in the chest and body with a knife, causing her death.
Prosecutors had recommended a sentence of 25 years to life in prison, while the court had indicated it would impose 20 years to life. That sentencing did not move forward because of the finding that Glaudin is not mentally fit to proceed.
Rockland County Court Judge Djinsad Desir ruled that Glaudin lacks the capacity to proceed, halting what had been scheduled as his sentencing date. On Thursday, Feb. 26, the judge ordered that Glaudin be placed in the custody of the state Office of Mental Health for care and treatment in a secure facility.
“The defendant will remain confined in a secure facility where he cannot pose a danger to others," Walsh said on Friday.
The investigation into Wilson’s killing was conducted by the Spring Valley Police Department. The case was prosecuted by Deputy Chief Assistant District Attorney Dominic Crispino.
Glaudin had also been free without bail on an unrelated attempted rape charge at the time of the 2020 stabbing, a detail that sparked intense public debate in the aftermath of Wilson’s death.
For now, instead of heading to state prison, Glaudin will remain in a secure mental health facility under state supervision.
