Charlton- Michael Ross Pintacura, 70, an avid collector of many interests and history buff, died on Thanksgiving Day at Life Care Center of Auburn. Mike will be sorely missed by his sister, Janice Kay Kerber, and her husband, Ken, of Auburn. Before his failing health, Mike was a resident of the Charlton Housing Authority on Meadowview Drive, where he enjoyed many hours with friends sitting outside his back door. Originally from Chicago, Mike relocated to Massachusetts in 1985 to be close to his sister. Before retiring, Mike operated vacuum chambers in the optics industry. He graduated in 1975 from the University of Illinois at Chicago Circle with a double major in physics and classical civilization. Mike faced his many health challenges with heroic courage and grace, choosing to move forward rather than complain. He was an inspiration to all who knew him. A memorial service will be held at the convenience of the family. Memorial contributions may be made to the American Diabetes Association, 260 Cochituate Road #200, Framingham, MA 01701. The Shaw-Majercik Funeral Home, 48 School St., Webster, MA has been entrusted with his arrangements.  A guest book is available at www.shaw-majercik.com where you may post a condolence or light a candle
