Soon after Labor Day, during what East Hampton Town police called an illegal eviction, 12 university students from the island of Jamaica, working in East Hampton on J1 visas for the summer, lost many of their possessions, as well as thousands of dollars in cash. The thief, police believe, was an intermediary entrusted by the students to handle the lease arrangements. The 12, all living in a house on Oakview Highway in East Hampton, had each paid $500 security for the first two weeks of their lease and another $500 apiece for the last two.
