Nothing is known about Josephine's life prior to or as the outbreak began aside that she was Elijah's sister.
After Elijah, Negan, Gabriel, and Maggie encounter Teresa in the woods and put her down, Maggie identifies Teresa as the best friend of Elijah's sister. Maggie warns Elijah that his sister is likely wandering around the area somewhere as well and promises to get revenge upon the Reapers for the murders of her and the rest of their people. Elijah promises to kill the Reaper that had murdered his sister personally.
Later, as the group are walking with a horde to destroy the Reapers at Meridian, Elijah spots his sister walking amongst the dead. Elijah silently breaks down in tears, but he is unable to do anything about it without breaking his cover.
It's revealed that Brandon Carver was the one who killed her. When Elijah confronts Carver over his sister's murder, Carver shows no care or remorse for his actions. During the stand-off with the Reapers, Elijah attempts to exact revenge on Carver for Josephine's murder but collapses. As the other Reapers leave, Elijah reminds Maggie of her promise to make all of the Reapers pay for what they did to Josephine and the others. Maggie shoots Boone and Washington dead before killing Carver with one of Elijah's kamas, finally getting revenge for Josephine's murder.
