Cold Squad - Season 2 (1998)

While Ali and Logozzo investigate the murder of retired teacher, they are surprised to learn that, after a stroke, his behavior had changed drastically, and he'd gone from being a mild-mannered school teacher to a sex fiend who went to swinger parties.

Ali reopens a closed case after she is shown a police video that indicates forensic malfeasance by the lead detective and the profiler.

When a man comes to the station with a box containing a blood-stained dress with a bullet hole, Ali and Tony investigate a possible murder on the college campus in 1964. They discover the victim wasn't who she appeared to be.

When a Chinese teenager is found hanging in a jail cell the morning after being arrested, Ali and Tony investigate the similarities with another jail cell hanging 20 years before, when the police department was being investigated for brutality.

Ali and Tony check out the story of an informant who claims he knows who killed a tow truck operator in 1991. Their case turns on the testimony of a woman who was a drug addict then, and who is now a hyper-religious housewife.

When an abandoned warehouse is being torn down, a headless corpse is discovered sealed in an interior wall. Tony concludes that the body is an industrialist missing since July 1972.

When a young woman claims to have a 17-year-old "recovered memory" of her sister's murder, the whole squad tries to sort through the family's secrets. Meanwhile, Ali attempts to get a confession from a terminally ill man long suspected of being a hit-man.

Firemen responding to a house fire find a child's picture displayed on a computer. Ali's attention is aroused when the child is identified as a boy who disappeared and was declared dead 15 years before, but in the picture he is older than when he disappeared.

After a body is found at a construction site excavation, Ali and Tony look into the case of an Anglican priest missing for two years. Simon asks Ali out on a date after accompanying her to an official function.

After a social worker asks Ali for her opinion on a possible child abuse case, Ali looks into the death of a little boy three years earlier in the same household.

Against her objections, Ali is given the job of investigating a doctor, whose husband died in a hospice, after one of her patients dies under nearly identical conditions in the same hospice.

Ali receives a letter from Denny Lavoie, the hit man who had died earlier, in which he tells her about the death of Nancy Seniuk a bag lady found dead in Stanley Park on August 17, 1980.
