This is just very sad. Yesterday we mentioned that Robin Roberts left Good Morning America a day early to go and visit her ailing mother, Lucimarian, before the host undergoes bone marrow surgery. Today, we've learned that Lucimarian Roberts died Thursday at the age of 88. ABC News is reporting that Roberts was with her mother in Mississippi at the time of her death. "Robin arrived home with her sister Sally-Ann, forging through flooded and blocked roads to be with her beloved mother in time to see her," Tom Cibrowski executive producer of GMA wrote in an e-mail to staffers this morning. 

As we noted yesterday, Roberts announced she has myelodysplastic syndrome (MDS) in June and is on leave from GMA as she begins treatment.
