In 2011, Kalinowski was hired by the Framingham Public Schools to teach social studies at Cameron Middle School.
On Aug. 25, at 7:57 p.m. Kalinowski submitted his resignation to Cameron Principal Michelle Melick said Framingham Superintendent of Schools Stacy Scott in a written statement very early Sunday morning.
As of Saturday night, Sept. 21, Kalinowski was still listed on the website as a teacher.
Kalinowski was not employed with the school system when he was indicted, but did work for the school system during New Mexico's Regulation and Licensing Department's two-year investigation.
Scott in his email to Patch wrote "while I believe an investigation is being restarted, it does not appear that any indictments or convictions have occurred."
A criminal summons was issued ordering Kalinowski, 68, to appear in the First Judicial District Court in Santa Fe for an arraignment on Oct. 7, at 10 a.m.
Each count against Kalinowski is a second-degree felony carrying a maximum penalty of nine years in prison.
The case is being handled by the New Mexico Regulation and Licensing Department’s Special Prosecutor Scott Mullins under the jurisdiction of First Judicial District Attorney Angela Pacheco.
Kalinowki, who lives in Duxbury, talked to a New Mexico TV station about the case. Click here to watch.
The case involved Kalinowski's life as a homebuilder in New Mexico.
Scott said references were checked prior to Kalinowski being hired with Framingham Public Schools.
"Pursuant to MA law at that time, a MA CORI was completed, said Scott. A Massachusetts CORI only reports offenses committed in Massachusetts, not in any of the other 49 states.
In 2012, Massachusetts law was changed to require national fingerprints for school employees.
Scott said the state "has not provided steps to schools for processing the fingerprints."
Under the new 2012 law, new teachers, school employees, bus drivers, early education and care and out-of-school care providers, must undergo state and national background checks starting in the 2013-14 school year.
The 2012 law also called for all current employees to undergo national background checks before the start of the 2016-17 school year.
