Erik Menendez previously slammed Murphy for his "vile and appalling character portrayals of Lyle and of me and disheartening slander." Murphy shot back, saying the brothers should be "sending me flowers" for the "outpouring of interest" in their case.

Erik Menendez and his brother, Lyle, have spent more than 35 years prison for killings their parents in 1989 in a case that over the past year has gained renewed public attention following the release of Netflix's "Monsters: The Lyle and Erik Menendez Story" and various documentaries.
