Blanchard Glaudin, 25, is charged with second-degree murder in the Tuesday stabbing of Sandra Wilson inside the Finkelstein Memorial Library in Spring Valley, New York, Rockland County District Attorney Thomas E. Walsh II said.
Spring Valley Police Chief Paul Modica said Glaudin stabbed Wilson after she told him to turn his music down.
“She was at the computer terminals and told him he had to turn it down,” Modica said. “That was it.”
Glaudin tried fleeing the building but was hit by a chair and restrained by several people. He is being held without bail.
The killing happened several miles from the nearby Hasidic Jewish village of Monsey, where five people were injured in the December machete attack.
Grafton Thomas, 37, of Greenwood Lake, N.Y., allegedly entered the home of a rabbi during a Hanukkah celebration prior to the anti-Semitic attack.
