Notorious murderer and cult leader 83-year-old Charles Manson died of natural causes on Sunday evening, according to prison officials in California.

ABC News reports that Manson shocked the world with a series of brutal murders and his face became a symbol of evil for many as he displayed seemingly no remorse and made dark, menacing statements.

He was deemed responsible for a two-day murderous rampage through southern California in August 1969 that left seven people dead, according to ABC News.

Pregnant actress Sharon Tate, hairstylist Jay Sebring, heiress Abigail Folger, writer Wojciech Frykowski and teenager Steven Parent, were killed at Tate's rental home on Aug. 9.

The five were murdered in the California home Tate rented with her husband, Hollywood director Roman Polanski, in the secluded neighborhood of Benedict Canyon. The next day, Leno and Rosemary LaBianca were killed at their home.

While Manson didn't commit the killings himself, reports say he commanded others to do so.

Prosecutors said he handed out knives and told his followers to commit savage murders of high-profile people around Los Angeles in a bid to start a race war. All seven victims were brutally stabbed.
