Exhibit A: Secrets of Forensic Science

On Remembrance Day, in a wealthy suburb, a German matron is found beaten and brutally murdered. An autopsy reveals that the real cause of death is that she's been shot in such a way as to conceal this fact. Firearms expert Sam Barbetta inspects the bullets and determines that the murder weapon was homemade - the bullets can't be traced! With firearms experts stymied, detectives enlist other experts to turn up a suspect. A forensic biologist deciphers the bloodstain pattern at the crime scene to determine the nature of the attack. Now the investigators can zero in on a suspect. When a forensic accountant delves into the suspect's financial circumstances, he discovers a possible financial motive for the murder. But the entire case hinges on finding the homemade gun. Can investigators and a firearms expert crack the case and pin the brutal crime on a calculating murderer?

An ex-model is found dead by her recent ex-boyfriend, Jeff. The victim is laid out on the bed fully clothed, her hands folded across her chest in an "at rest" position. Jeff allegedly gets another shock when he finds the message "Jeff You're Next" scrawled in lipstick across the living room mirror. Investigators discover that Jeff had intended to move out that day. The question becomes, did this woman commit suicide and write the message to spook her ex-lover, or is it murder? A forensic document examiner determines that the handwriting on the mirror does not match the dead woman's. So did the ex-lover kill her and write the note to turn suspicion away from himself? Or did a jealous suitor murder the woman and now have it in for her boyfriend? Detectives uncover a startling story. But it takes an ingenious ploy and the skills of a top handwriting expert to close the book on a murderer.

Shortly after a young working student moves into a new apartment, she suspects someone has been visiting when shes not there. To quell her suspicions, she places a bottle just inside the door as she leaves for work. When she returns, the chain is still on the door, but the bottle has been moved. She gets the shock of a lifetime when a stranger is found dead in her bathtub.

Two men are shot and killed in a botched robbery at a local community centre after catching two thieves in the act. The murders occur in the boiler room. One of the bullets has pierced a drum of purple air conditioning fluid and so the floor is a wet, sticky mess of blood and purple fluid. In a flash of forensic intuition, firearms specialist Finn Nielson picks a sliver of wood off the floor of the murder scene. Back at the Centre of Forensic Sciences, he identifies the sliver as a broken piece from the butt end of .300 caliber savage rifle. Police investigate recent robberies and find out that three guns have been stolen in the previous week only blocks from the community centre. The rifle was then sold to another man whom the police arrest. But they now must find out which of the two thieves actually pulled the trigger. To add to the confusion, each of the two suspects tells a contradictory tale of what happened. A forensic biologist analyzes the blood on the clothing of the two suspects' clothing to determine who will pay the price for this tragic crime.

Dr. Cheryl Wagner treats her first ever female patient with AIDS. Only days later she treats a second woman with the same affliction - then, a third. Incredibly, all are infected by the same man. At Dr. Wagner's insistence, public health officials issue a restraining order, forbidding the man from having sex. He then infects another woman.

It happened on a native reserve in Southern Ontario. That's where two masked men broke into a house in the middle of the night. Living there were a husband and wife who owned a profitable gas station/restaurant. When their demands for money aren't complied to quickly enough, the masked men open fire, grab the money and flee. By the time ambulance crews take the man to hospital, the crime scene is so trampled and smudged that the only uncontaminated clue is a sneaker print in the snow. Jim Eadie, an OPP forensic identification officer and a leading expert on footprints, makes a plaster mold of the sneaker print in the snow. But with running shoes such a popular choice and with the overwhelming number of brands on the market, can the expert pinpoint this particular print in a "haystack" of running shoes? With the help of a forensic biologist and a firearms expert, see how police are able to stop the killers cold in their tracks.

When women are being drugged and sexually assaulted, a forensic toxicologist wrestles with his own integrity to nail the disgusting culprit.

A man drives 20 minutes along a super-highway and then murders his mother-in-law, allegedly while sleepwalking. Can a sleep expert determine if this is a bogus defense?

When a vivacious cheerleader is murdered and sexually assaulted, DNA profiling helps investigators exonerate the innocent and convict the guilty in a 13-year-old case.
