NAPANEE, Ont. -- Convicted killer Paul Bernardo will stand trial in October on a weapon possession charge laid in connection with an offence allegedly committed in a maximum-security prison.

Bernardo is facing one count of possession of a weapon, alleged to be a shank comprised of a screw and pen.

He appeared briefly via video link in a Napanee, Ont., court today, where his trial was set for Oct. 5.

Court documents show the alleged offence occurred Feb. 9 at a prison in Bath, Ont.

Bernardo, one of Canada's most infamous killers, was arrested in the 1990s on allegations that he raped and murdered multiple teenage girls at his Ontario home.

His 1995 trial for the deaths of 14-year-old Leslie Mahaffy and 15-year-old Kristen French horrified Canadians as lawyers presented videotaped evidence of his repeated brutal attacks on the teenagers.

Bernardo was eventually convicted of first-degree murder, kidnapping, forcible confinement and aggravated sexual assault in both cases and sentenced to life without the possibility of parole for 25 years.

He was later convicted of manslaughter in the death of Tammy Homolka, the younger sister of his wife Karla Homolka, who was convicted of having roles in all three killings and served a 12-year prison sentence after striking a deal with prosecutors.

After admitting to raping 14 other women in and around Toronto, Bernardo was labelled a dangerous offender, which all but ensures he will stay behind bars for life.
