The family of Sandra Wilson, a security guard, is now suing the East Ramapo school district, her accused killer, and Finkelstein Memorial Library.

Wilson's son claims his mother notified Finkelstein library officials of Blanchard Glaudin's harassment and unwanted romantic advances toward her.

He argues the murder could have been prevented. Wilson was killed in February after telling Glaudin to lower his music. Glaudin is charged with second-degree murder.

Wilson is survived by her mother, Shirley Wilson, and her two sons and daughter.

In a statement, the East Ramapo school district says it cannot comment on pending litigation.
