Erik Menendez and his brother, Lyle, have spent more than 35 years in prison for killing 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.

Erik Menendez has been hospitalised with kidney stones and now the famed parent killer’s lawyer is calling for his client’s release ahead of an August parole hearing, according to a report.
