More than four decades behind bars did not curb Charles Manson’s violence or bizarre behavior: He got in trouble more than 100 times for assaults, making threats and even trying to start a fire and flood the prison.

The cult leader and convicted killer, who ordered his followers to murder seven people in 1969, died Monday of natural causes. He was 83.

Manson remained a menace to all around him even after going to prison. While serving his life sentence, Manson attacked prison staff, got drugs and phones into his cell and even tried to escape using a hot-air balloon, according to the Los Angeles Times.
