The Netflix series about the American serial killer and cannibal Jeffrey Dahmer are said to have disturbed his father Lionel.
The 86-year-old, who lives in seclusion in rural Ohio, is said to be considering legal action because the producers of the series Dahmer: Monster: The Jeffrey Dahmer Story and Conversations With A Killer: The Jeffrey Dahmer have not released tapes before the premiere in recent weeks sought contact with him.
As a supervisor of the former chemist told the American "Sun", the producers are said to have processed recordings of his son's conversations with his defense lawyers without Dahmer's knowledge or consent.
Jeffrey Dahmer, also known as the "Milwaukee Monster", killed, dismembered and sometimes ate at least 17 young, mostly homosexual men between 1978 and 1987.
After his arrest in 1991, he confessed to the crimes.
Three years later, the former soldier, who was stationed in Baumholder in Rhineland-Palatinate in the late 1970s, was killed in prison by a fellow inmate.
His father, Lionel Dahmer, also supported the killer during the sensational criminal trial in Milwaukee (Wisconsin).
