Former town manager Michael Coughlin is recuperating at Spaulding Rehabilitation Hospital after a June 4 stroke that left his right side paralyzed. Coughlin, who was fired in March 2012 and is suing to get rehired, said he was driving when his right side went numb. His wife, Bernadette, took him to the hospital, where he initially seemed fine but when he emerged from a CAT scan, he couldn’t move, he said. Coughlin, who turned 55 on June 12, said his speech is coming back and he is re-learning how to use his arms and legs. Coughlin said he expects to be released from the hospital this week.
