A family of four rescued from their sailboat after the youngest of two children became seriously ill are due to return to California on Wednesday aboard a U.S. warship that picked them up over the weekend, Navy and Coast Guard officials said. Military officials declined on Monday to give any details on the medical condition of 1-year-old Lyra Kaufman except to say that she, her 3-year-old sister, Cora, and their parents, Eric and Charlotte Kaufman, were all safe as they headed back to port in San Diego.
