Serial rapist and murderer, Paul Bernardo was accused of possessing a homemade shank back in February 2018. He'd made it from a screw and a pen handle at the maximum-security Millhaven Institution in Bath, Ontario where he is serving his life sentence. He's now on trial for a weapons possession charge.

The 54-year-old known as the "Scarborough rapist" was convicted in 1995 of the murder of two teenage girls and several sexual assaults. He and his equally as notorious ex-wife, Karla Homolka participated in horrific, sadistic crimes.

There was also 15-year-old, Kristen French of St. Catharines, Ontario who was tortured and killed after being held captive for three days.Homolka's own sister was also one of the victims.  Tammy Homolka was only 15 years old when she was drugged, sexually assaulted and killed by the pair while she was unconscious. Bernardo was labeled a dangerous offender due to his heinous crimes and was not to be eligible for parole until he had served 25 years of his sentence after being arrested in 1993.

Homolka, on the other hand, testified against her then-husband and in return only got 12 years. She's now living free and has children. Bernardo's 25-year mark has passed and he has a parole hearing scheduled for later this month. He had said he wanted to get this weapons possession trial out of the way before then. His lawyer believes he will be acquitted.
