Shea's family said in an obituary posted in local newspapers that he died Friday. His funeral is set for Friday at St. James Church in Manchester.
Shea was a state representative in 1961 and 1962 and a state Superior Court judge from 1973 to 1980. He left the bench to become vice president and claim counsel for Aetna.
Shea also was a private practice lawyer. The Journal Inquirer reports that he won a 1968 U.S. Supreme Court case that resulted in his client's murder conviction being overturned. Shea represented Roy Darwin Sr. of Andover, who had been convicted of the 1963 killing of 17-year-old Hope Fern Rothwell of Bolton.
