This story just keeps getting sadder and sadder.

The same night (Friday) that Farrah Fawcett's personal doc Farrah's Story aired, In Touch reports that Redmond O'Neal was allowed to leave Twin Towers correctional facility to visit with his sick mom. An insider says that "he went to her condo to spend time with her."

Ryan O'Neal has recently voiced that "Farrah's condition has gotten worse in the last couple of days." In the documentary, he told Redmond: "Live your life as a tribute to your mother."

During the visit with Farrah, Redmond had his legs shackled and wore a jumpsuit.

Our hearts go out to this family during this difficult time...
