Experts are still trying to determine the source of a foul odor that has been emanating from Laurel Plains Elementary School for more than a week.

Classes were moved to Clarkstown South High School last Monday after students were complaining to their parents that the smell in the school was making them sick.

After extensive tests, experts told a packed PTA meeting last night that they still haven't found the source of the smell.

Today, the school district said several teachers were symptom-free at the building, but it's still likely students will stay at the high school throughout the week.
