Estranged mother of Gilbert Arenas passes away

Gilbert Arenas’s troubles were magnified recently, when he discovered that his estranged mother, Mary Francis Robinson, died in Miami.

Robinson passed away on March 13, but Arenas didn’t find out until a few days later, according to multiple sources. The cause of her death is not known.

Arenas wasn’t close to his mother, who abandoned him at young age and left him to be raised by his father, Gilbert Sr., from the time that he was 3.
