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.

Menendez, who is incarcerated at a San Diego prison, was taken to an outside medical facility on July 18, where he remains in fair condition, an official said.

Erik Menendez has reportedly been diagnosed with a ‘serious’ health condition and hospitalised just weeks before a parole hearing he and his brother have long awaited.
