KINGSTON, Ont. - Police have been called in to help investigate the death of a prisoner at Millhaven Institution, near Kingston, Ont.

Correctional staff at the maximum-security prison found 59-year-old Vincente Orozco unresponsive in his cell Wednesday.

Efforts to revive him failed.

Orozco began serving a life sentence for second-degree murder three weeks ago.

It was for the 2003 death of a sex trade worker in Toronto.
