Public school teacher, EMT busted for selling heroin

A former substitute teacher and Brooklyn EMT were busted after a five-month investigation revealed they were selling heroin, police sources said.

Lisa Testa, 33, who hasn’t worked for the Department of Education since 2008, was arrested outside of her Bensonhurst home on 2 p.m. Thursday while waiting for her supplier, cops said.

EMT Joseph Meyer, 26, was also waiting for the supplier, Michael Ortiz, 26, outside the same home, the sources said.

The investigation started in December 2013 after detectives received a written statement that claimed the school teacher was addicted to pills and heroin — and was selling the drugs, the sources said.

Testa, who sold assorted pills including heroin, clonazepam and suboxone to undercover cops several times over the course of the investigation, the sources said.

Suboxone is an opioid suppressant that treats effects of narcotic addiction.

Ortiz was caught carrying at least 80 glassines of heroin at the time of his arrest, cops said.

He was slapped with possession with intent to sell and criminal sale of a controlled substance within 1000 feet of a school — but it wasn’t immediately clear if those transactions were made near the school where she taught, cops said.

Testa was charged with criminal possession and sale of a controlled substance.

The duo weren’t working together but shared the same supplier, the sources said.
