Island residents sue US, saying military made them sick

Nearly 40 years ago, Hermogenes Marrero was a teenage U.S. Marine, stationed as a security guard on the tiny American island of Vieques, off the coast of Puerto Rico. Marrero says he's been sick ever since. At age 57, the former Marine sergeant is nearly blind, needs an oxygen tank, has Lou Gehrig's disease and crippling back problems, and sometimes needs a wheelchair. "I'd go out to the firing range, and sometimes I'd start bleeding automatically from my nose," he said in an interview to air on Monday night's "Campbell Brown." "I said, 'My God, why am I bleeding?' So then I'd leave the range, and it stops. I come back, and maybe I'm vomiting now. I used to get diarrhea, pains in my stomach all the time. Headaches -- I mean, tremendous headaches. My vision, I used to get blurry." The decorated former Marine is now the star witness in a multibillion-dollar lawsuit by more than 7,000 residents of this Caribbean island -- about three-quarters of its population -- who say that what the U.S. military did on Vieques has made them sick.
