Officials at an elementary school in Fallsburg, New York, are questioning staff after heroin was found in one of the bathroom there—for the second time.

According to NBC, officials found a baggie of the drug in the boys' bathroom at Benjamin Cosor Elementary School on February 11, just weeks after finding a similar baggie—plus needles—just weeks prior.

Surveillance footage reveals eight adults appear to have used the bathroom before the discovery, one of whom is a contract occupational therapist at the school and volunteered a urine sample. The others—six teachers and an aide—have sought lawyers, a move that rankled the Fallsburg police chief, Simmie Williams.

"If you got nothing to hide, give me some urine," he told the Times Herald-Record. "Let's clear the teachers' names who are taking care of these babies for six or seven hours a day."
