Paul Bernardo will not face trial on one count of weapons possession after the Crown withdrew the charge this morning.
Authorities accused the maximum-security inmate of possessing a "shank" — consisting of a screw with a pen as a handle — in prison in February.
The Crown says the charge was withdrawn because there was no reasonable prospect of conviction.
The 54-year-old killer and serial rapist, had said he wanted to get the trial done before a parole hearing scheduled for later this month.
Also known as the "Scarborough rapist,'" Bernardo was convicted in 1995 of the first-degree murders of two teen girls and numerous sexual assaults.
He was labelled a dangerous offender and was not to be eligible for parole until he had served 25 years since his arrest in southern Ontario in early 1993.
