Canadian Case Studies: Inquiries and Forensic Science Errors in Wrongful Convictions

Comprehensive vocabulary flashcards reviewing Canadian wrongful conviction cases, including the Milgaard and Morin cases, the Kaufman Report recommendations, and the Goudge Inquiry into pediatric forensic pathology.

David Milgaard

A 16-year-old transient who was wrongfully convicted of first-degree murder in 1970 for the death of Gail Miller, spent 23 years in a federal penitentiary, and was officially exonerated by DNA evidence in 1997.

Gail Miller

A Saskatoon nursing assistant found murdered in a snowbank in an alley on January 31, 1969; she suffered over two dozen stab and slash wounds in -42°C weather and had evidence of sexual assault on her clothing.

Larry Fisher

A convicted serial rapist who resided in the basement of Albert Cadrain's home and took the same bus as Gail Miller; in 1997, DNA testing linked him to Miller's murder with a 1 in 950,000,000,000,000 random match probability, resulting in his conviction in 1999.

Dr. James Ferris

A noted forensic pathologist who reviewed the David Milgaard case and concluded in an expert report that there was no physical evidence linking Milgaard to the murder of Gail Miller.

Guy Paul Morin

A 23-year-old furniture manufacturer with no criminal record who was wrongfully convicted of the 1984 murder of his nine-year-old neighbor Christine Jessop based on flawed hair and fiber comparisons and jailhouse informant testimony.

Christine Jessop

A nine-year-old girl who vanished on October 3, 1984, after arriving home from school; her body was discovered on December 31, 1984, 56 kilometers away, bearing multiple stab wounds.

Centre of Forensic Sciences (CFS)

The forensic laboratory whose analysts testified that hairs and fibers connected Guy Paul Morin to Christine Jessop and his car, despite the existence of known in-house fiber contamination within the facility.

Mr. X (Morin Case)

A diagnosed sociopath and jailhouse informant who provided unreliable testimony claiming he overheard Guy Paul Morin confess to Christine Jessop's murder while in custody.

Calvin Hoover

A Jessop family acquaintance who died by suicide in 2015 and was definitively identified in October 2020 as Christine Jessop's killer through forensic genetic genealogy linking his DNA to semen on her clothing.

Forensic Genetic Genealogy

An investigative method combining genealogical research with DNA profiling from public genealogy databases, used to construct family trees and resolve the 36-year cold case of Christine Jessop.

Tunnel Vision

The single-minded and overly narrow focus on a particular investigative or prosecutorial theory, which unreasonably colours the evaluation of incoming information and ignores alternative hypotheses.

Kaufman Recommendation #2

A policy stating that evidence demonstrating only that an accused cannot be excluded as the donor of an unknown hair has insufficient probative value to justify admissibility as circumstantial guilt.

Kaufman Recommendation #9

A guideline warning that forensic terms such as 'match' and 'consistent with' are demonstrably misleading to juries because they do not represent scientifically falsifiable conclusions.

Kaufman Recommendation #11

The instruction that forensic scientists must follow the scientific method by vigorously attempting to challenge or disprove an investigative hypothesis, particularly when suspect-crime associations are involved.

Successive Classification of Fiber Evidence

A hierarchical analytical model that applies physical characterization (type, cross section, dimensions) followed by chemical characterization (surface, colorants) to progressively reduce potential evidence sources.

Dr. Charles Smith

The former head pediatric forensic pathologist at Toronto's Hospital for Sick Children (1982–2003) who performed over 1,000 autopsies, resulting in questionable findings in 20 cases and 13 wrongful murder convictions.

Goudge Inquiry (2008)

An Ontario public inquiry examining flawed pediatric forensic pathology and unscientific autopsies conducted by Dr. Charles Smith, which exposed the dangers of overrelying on unchallenged expert witnesses.

Tammy Marquardt

A mother wrongfully convicted of second-degree murder after Dr. Charles Smith gave unscientific and illogical conclusions regarding her child's cause of death.

William Mullins-Johnson

A man who served 12 years in prison after being wrongfully convicted of child sexual assault and murder due to flawed forensic pathology findings by Dr. Charles Smith.
