What happened to Ndulue's first wife when he died?

Ozoemena went to pay her respects to her dead husband, and then went back to her tent and died.

"Ozoemena was, as you know, too old to attend Ndulue during his illness. His younger wives did that. When he died this morning, one of these women went to Ozoemena's hut and told her. She rose from her mat, took her stick and walked over to the obi. She knelt on her knees and hands at the threshold and called her husband, who was laid on a mat. 'Ogbuefi Ndulue,' she called, three times, and went back to her hut. When the youngest wife went to call her again to be present at the washing of the body, she found her lying on the mat, dead."
