Convicted Canadian serial killer Robert Pickton who killed over 20 women has been hospitalized and is in a life-threatening condition after an assault at a Quebec prison, authorities said Tuesday.
The 74-year-old Pickton was convicted of six counts of second-degree murder and sentenced to life in prison in 2007, with the maximum parole ineligibility period of 25 years, after being charged with the murders of 26 women.
