In 1986, Toronto and the rest of Canada were stunned by the Alison Parrott case. More than a decade would pass before this tragic case would be solved thanks to the perseverance of the newly formed "Cold Case Squad." In the meantime, the horror of Alison's fate changed many parents' views towards the safety of their children and ushered in an era of educating kids on street smarts. In 1999, due to sophisticated DNA techniques, police finally nabbed the killer Francis Carl Roy and closed one of Toronto's most chilling cases.

A quiet May evening is shattered by the blast of a huge explosion and minutes later part of a quiet urban neighborhood is up in flames. The police are confronted with hate slogans spray-painted onto what is left of a garage door. Is this a hate crime and if so, who was the target?

"Tragedy of Errors" focuses on the forensic skills of two blood spattering experts, who not only teach at the police college in Ottawa, but are still active in the field. The difference between academic knowledge and the reality of an actual crime scene is brought to life in this intriguing episode. As the story unfolds we witness how these investigators are able to decipher a story from bloodstain patterns the way archaeologists read ancient hieroglyphics.

An intruder breaks into a family home in a well-to-do Calgary neighbourhood. When he's confronted by the owner, the burglar stabs him to death. The killer flees leaving behind several smudged prints on a window that appear to be left by a pair of gloves. Can these help nail a murderer?

A fisherman, trawling off the English coast, comes upon what appears to be a large fish in his net. But it turns out to be a dead body. The body is wearing shoes and a Rolex watch, but has no I.D. - is it murder or suicide? So begins the Albert Walker case - the story of a man who was wanted for embezzlement in Canada, fled to England, then killed a man so that he could steal his identity. This episode recounts one of the strangest, most intriguing cases of mistaken identities in the recent history of crime.

In 1974, this band of gentlemanly bank robbers from Canada stole $700,000 in gold bricks from a storage warehouse at Ottawa International Airport. It was and still is Canada's biggest-ever gold robbery. The gang was eventually caught, but escaped before the end of the 70's. After escaping, all three moved to the US and regrouped, beginning an incredible string of more than 50 bank robberies. Their MO gave the group their unique name - one member carried a stopwatch and would time their hold-ups based on the interesting supposition that if they weren't out of a bank in 90 seconds their chances of getting apprehended were mathematically higher. The "Stopwatch" story is a fascinating part of Canadian criminal history.

Two young sisters are murdered and recovered DNA points a "finger from the grave" at the killer. The police determine the crime scene had been staged to look like a "break and enter" and the primary motive for the crime was homicide not theft.

As sophisticated as forensic science has become, the human factor opens the door to fallibility. "Double Jeopardy" presents a tragic example of what happens when forensic science fails. In this case, a forensic scientist misinterprets the facts surrounding a shooting, thereby allowing the guilty party to walk free. But the victim's mother won't let the case rest. Eventually she gathers enough evidence to reopen the case - and prove it was murder. But the murderer can't be tried again because of the laws of "Double Jeopardy."

A serial rapist in Lafayette, Louisiana is finally caught thanks to a tenacious, local investigator and a unique Canadian forensic scientist, who developed "geographic profiling."
