Bethel Board of Education chairman Larry Craybas is stepping down as he battles leukemia. The Republican resigned last week after more than a decade volunteering his time on the board. The selectmen will fill the vacancy. Vice chair Melanie O’Brien will serve as acting chair until new officers are appointed. As chairman, Craybas oversaw the approval of the 65-point-8 million dollar renovations to Rockwell and Johnson schools and helped it get through the proper approvals. He is being treated at the Memorial Sloan Kettering Cancer Center in New York City.
