Former Broken Ground teacher charged with mailing drugs to gang members in state prison

A former Broken Ground School teacher has been charged with mailing drugs to members of a white supremacist gang who are inmates at the state prison in Concord.

Peggy Sinclair, 50, who was arrested with her former student Matthew Peters in April, is now facing charges for possessing controlled drugs and mailing them to the prison. The police said she conspired with 22-year-old Peters – who is her boyfriend, an inmate at the state prison and a “street captain” of the prison gang Brotherhood of White Warriors – to smuggle drugs into the prison.

Sinclair mailed buprenorphine to Peters at the prison using the U.S. Postal Service, the police said.

In April, Sinclair and Peters were arrested together and charged with drug possession. The drug charges from Sinclair’s April arrest were dropped, after her attorney presented evidence that she had a valid prescription for the prescription drugs found in her purse. Peters is still facing drug charges for that arrest.

The Concord police said a multi-agency investigation into a prison-based Brotherhood of White Warriors Gang revealed that drugs were mailed to the prison, and a forensic laboratory connected Sinclair to envelopes containing the drugs. She is one of Peters’s girlfriends, the police said, and she is also an associate of other gang members inside the prison.

The Concord School District confirmed last week that Sinclair would not return to her position teaching fifth grade at Broken Ground School.

This morning, Sinclair turned herself into the police. She is scheduled to be arraigned this morning at Concord’s district court.
