FALLSBURG - A teacher at the center of the Benjamin Cosor Elementary School heroin probe is allegedly refusing to take a drug test.

The Sullivan County district attorney says that one of seven teachers refused to be tested for heroin after being seen on police surveillance video going into a men's bathroom at the school where empty heroin bags and needles were found.

On Friday, the DA confirmed that five out of the seven teachers tested negative for heroin, with one test still pending.

"These six staff members, after initially refusing to submit to urine tests at the request of Fallsburg police, have now cooperated and aided us in our ongoing attempt to determine the source of the these drugs," said the DA.

The school district said in a letter that a series of small meetings is being planned in an effort to mend the broken trust within the community.
