Alleged Winnipeg serial killer Shawn Cameron Lamb has had his parole revoked or denied five times since 2001, documents show.

Lamb, 52, has 109 criminal convictions, including sex assault, uttering death threats and theft, according to court documents. He has done time in various jails across the country and his parole was revoked or denied five times since 2001, according to parole board documents obtained by CTV News.

Lamb is now facing three counts of second-degree murder in the deaths of Lorna Blacksmith, 18, Carolyn Sinclair, 25, and Tanya Nepinak, 31.

All three aboriginal women had been missing for some time. Blacksmith and Sinclair’s bodies were found discarded and wrapped in plastic or bags. Nepinak’s body has not been recovered, but police said they have enough evidence to conclude that she has been murdered.

Lamb, who is originally from Ontario, has been described as a man with anger issues and a history of violent behaviour in court documents.
