Monster” Season 3 has yet to set a premiere date, but Season 4 of the hit Netflix anthology series is already in the works. Variety has learned from sources that a fourth season focused on the Lizzie Borden case is currently prepping for a potential fall shoot,

Previous seasons of the Ryan Murphy-produced "Monster" have focused on serial killer Jeffrey Dahmer and the Menendez brothers case. Erik and Lyle Menendez, convicted of killing their parents, were recently resentenced and became eligible for parole after more than three decades behind bars.

Monster' s fourth season may follow the case of Lizzie Borden — a young woman from Fall River, Massachusetts, who was accused of murdering her father and stepmother with an axe in their home in 1892. The gruesome murders attracted nationwide attention and spurred a haunting nursery rhyme referencing "forty whacks" with a murderous axe.
