NEW LONDON, Conn. AP – After drug giant Pfizer Inc. announced that it was opening a new research center here, city officials aggressively moved to acquire surrounding land for an economic development project – triggering an epic fight over eminent domain that reached the U.S. Supreme Court and ended with residents being forced from their homes.

But the land where the homes once stood has remained undeveloped, and the community took another hit last week when Pfizer, a major economic engine in the city and its largest taxpayer, announced plans to close the $350 million research center and relocate about 1,500 workers to nearby Groton.
