The unsolved murder cases from the first five films
Tripe Chicago Homicide: This is the only link that Nica clicks on and its dated "December 1988", which would be one month after the events of the first movie and it shows a black and white still photo of 6 year old Andy and his Good Guy doll, Chucky. I don't get why it's called "Triple Chicago Homicide", shouldn't it be "Quadruple Chicago Homicide"? There were 4 people killed, not just 3; Maggie, Eddie, John, and Andy's doctor.
Double Chicago Homicide: This is from the second film. I think they're referring to Andy's foster parents but his teacher and foster guidance counselor were also murdered, too. Then you had Mattson and that factory security maintenance man as well. I wonder if they ever found his body after 8 years?
Kent Military Homicide: This one is pretty obvious. Although how the hell did Andy manage to graduate if we was framed for the doll's murders, as well as the deaths that took place inside the campus? Most people thought that he was arrested at the end when that security guard was found dead at the carnival.
Niagara Falls and Hackensack Homicides: These are from the fourth one, which I thought took place in North Carolina, at the beginning of the film. I know they go on a road trip to New Jersey; where the murders take place at that love hotel and the Hackensack Cemetery.
Los Angeles Homicide: Obviously from the 5th one where that paparazzi, Redman, and a few others were murdered, at the hands of Chucky, Tiffany, and Glenda.
