Joan Kennedy, still alive and seen at ex-husband's funeral services.

In 2005, Boston police found a disoriented woman lying bleeding and alone on a Beacon Hill sidewalk after she had taken a drunken fall.

Joan Kennedy -- the first wife of the late Sen. Edward Kennedy -- was unrecognizable to the Good Samaritan who had helped her that rainy night.
The woman who called the ambulance later told Boston Magazine, "I had no idea who it was, that it was anything special."
Today, at 72 and living independently after struggling with a lifelong alcohol addiction, the mother of Kennedy's three children is still invisible as the world mourns the passing of the senator.
Trying "not to intrude" yet to honor the life of her ex-husband, Joan Kennedy attended the Thursday mass in the "big house" at the Kennedy compound, according to her sister Candace McMurrey of Houston, Texas.
"She feels it's very nice to be included in the final saying goodbye to him and she appreciates being included in that, because she was married to him for 25 years," McMurrey told ABCNews.com.
While her ex-husband fought a brain tumor at the Kennedy compound this summer, the once-striking blond who in the heyday of her beauty resembled "Mad Men's" lovely and lonely Betty Draper, rented the nearby home on Squaw Island that once belonged to her own wealthy family.
