Killer of Hells Angels recruit Greg Slewidge dies in prison

Michael Clairoux, 52, died Friday at Millhaven Institution after serving just over 1 year of a life sentence

One of the men convicted in the murder of Hells Angels recruit Greg Slewidge has died in prison, according to Correctional Service Canada (CSC).

Michael Clairoux, 52, had served just over one year of a life sentence when he died on Friday at Millhaven Institution, a maximum security prison outside Kingston, Ont. A news release from CSC did not disclose the circumstances of his death.

In January 2025, a jury in Perth, Ont., found Clairoux and Lee Marazzo guilty of planning and carrying out the killing of Slewidge, 39, more than five years earlier at a legal marijuana farm.

Prosecutors argued the two had been hired by a Hells Angels support club to murder Slewidge, whose father is a former Ontario Provincial Police officer and a regular anthem singer for the Ottawa Senators.

It was also alleged that Clairoux was himself a member of Hells Angels.

Clairoux's next of kin has been notified and CSC will be reviewing the circumstances of his death, CSC wrote in a news release Monday.
