MILLBURN, N.J. — Anonymous letters sent shock waves through the Glenwood Elementary School community with serious accusations. Postmarked out of St. Paul, Minnesota, the typewritten letters warn parents that their children are potential victims of sexual assault from "a group of adults" at the school.

The Millburn Police Department continues to investigate, but told the public that, "after a careful investigation into the allegations sent in a letter to the public about Glenwood School, has found the letter not to be credible."
