The driver of a van that transports special needs students to schools in Massachusetts allowed her boyfriend to sell drugs out of vehicle, according to authorities.

Rudencia Montes, 43, a driver for an educational nonprofit for special needs students, was arrested on Friday after an officer witnesses a drug deal involving the van she was driving, Framingham Police told Boston 25 News.

Montes was driving a white minivan that had a school sign on the roof when she turned into a park parking lot and another car pulled up next to the van, police said.

The driver of the car, Corrine Gentile, 33, was seen by an officer completing a drug deal with the passenger of the van, Juan Miranda-Ortiz, 33, Framingham police spokeswoman Patricia Grigas told Boston 25 News.

When police pulled over Gentile, they found an envelope containing two packets of heroin, authorities said. A subsequent traffic stop of Montes revealed an envelope inside the van that matched the one found earlier in Gentile's car, according to police.

Montes and Miranda-Ortiz were charged with distributing heroin, conspiracy to violate the state's drug laws and a park zone violation, while Gentile was charged with possession of heroin and conspiracy to commit a crime.
