Grief counselors are on hand at the town’s high school Tuesday.

“I am hoping that everyone will grieve with the families as I am doing,” Lindehurst Mayor Michael Lavorata told Hall. “People have a tendency to speculate as to what happened or what might have happened. I have no clue as to what happened.”
