Mother of Cuban who tried to reach the US in taxicab converted into vessel holds photo of her grandsons in Havana. Francisca Josefina Rey Serbelo holds a picture of her two grandsons in Havana June 8, 2005. Francisca's son Rafael Diaz, his wife and their two sons set sail along with other Cubans for the U.S. in a vintage blue Mercury 1949 taxicab converted into an unwieldy vessel. The makeshift boat, with a prow jutting out of the front and a taxi sign on the roof, was intercepted on Tuesday by the U.S. Coast Guard about 20 miles off Key West on the southern tip of Florida.
