FALLSBURG - Angry parents packed a meeting in search of answers as to why a group of Hudson Valley teachers, at the center of a drug probe, are still at the head of the class. 

Police say that heroin and hypodermic needles were found inside the faculty bathroom of the Benjamin Cosor Elementary School in the Sullivan County town of Fallsburg last week. 

Seven staff members are reportedly under investigation after they were spotted on surveillance video outside the bathroom.

At first, all seven teachers agreed to be drug tested, but then later refused after hiring attorneys and consulting with union representatives. 

The district superintendent says the teachers will remain in the classroom while the investigation is ongoing.
