The DA’s office said these charges stem from her giving out pills, not selling them — which is still considered distribution. She was arrested on Monday.

Backler had worked in the North Andover Public Schools in different capacities from May 2011 to February 2015. She was a daily substitute teacher from May 2011 to April 2012, then worked as a long-term substitute from April 2012 to June 2013. She worked as a science teacher in the 2013-2014 year. She also worked as the school’s swim team coach.

At the time of her arrest, Backler was not an employee of the schools. A parent told the administrators, who then contacted the School Resource Officer for the North Andover Police. They say that this is an isolated event and it involved one student. 

Backler is scheduled for arraignment on Tuesday.
