Police are investigating the fatal shootings of well-known Boston-area real estate attorney/developer John Magee and his wife Geraldine, who were found dead by their daughter in their Andover, Massachusetts mansion Wednesday morning.

"The incident appears to be ... an isolated act. And the circumstances lead us to believe that there is no further threat to the Andover community," Andover Police Chief Brian Pattullo said. "I don't want to give out any specifics that may compromise our investigation."

Officials -- who said there was no history of trouble between John, 69, and Geraldine, 67 -- have classified the incident as a double homicide.
