A laptop containing personal information from thousands of blood donors–including Social Security numbers and medical information–was stolen from a local office of the American Red Cross, but officials said the information was encrypted. The data included matching names and birth dates of donors from Texas and Oklahoma, as well as donors’ sexual and disease histories. The laptop was one of three stolen from a locked closet in the Farmers Branch office of the American Red Cross in May, but the two others did not contain the personal information. There was no sign of forced entry, said Red Cross spokeswoman Audrey Lundy.
