An inmate who murdered jailed cult leader Roch Thériault in February, 2011, has been sentenced to life in prison.

Thériault was in prison for killing his wife by disembowelling her, and for chopping off the right arm of another wife with a chainsaw.

Canadian police say a man will appear in court in Moncton, N.B., today to face a first-degree murder charge in the death of former cult leader Roch Theriault.

Theriault, 63, was killed in an altercation with another inmate inside the correctional centre in Dorchester on Feb. 26.

Roch Thériault, the former doomsday cult leader who was killed in his cell over the weekend, paid dearly and often for his crimes, his lawyer says.

Infamous cult leader Roch Theriault was found dead inside his prison cell early Saturday.

A spokesman for Corrections Canada said there was evidence Theriault was the victim of an assault and that a murder investigation is now underway.

Charismatic and brutal, Roch Theriault chopped off the hand of one concubine and disembowelled his wife. Now his artwork is for sale online.

The prison artwork of a notorious Canadian killer is being offered for sale on an American website that promotes criminals as celebrities. The charismatic leader of a tiny religious group between 1977 and 1989, Roch Theriault chopped off the hand of one of his concubines and killed his wife by disembowelling her.

Cult leader Roch Theriault, who once used a meat cleaver to amputate the arm of a concubine, was denied parole Thursday on the grounds he represents an ongoing danger to society.

Canada came close to having its very own Jonestown or Manson family murders, says a Quebec woman who managed to flee the grasp of 1980s cult leader Roch Theriault after he cut off her right arm with a chainsaw.
