Editing Dragnet (franchise) (section)

==Actual cases==
The opening of "The story you are about to hear is true" is derived from the fact that many works in the franchise are transcribed from official LAPD case files. In some cases, the source material has been identified, including the following:

* "[[List_of_Dragnet_(radio_series)_episodes#1949_season|Sullivan Kidnapping – The Wolf]]" (Radio, 1949) – The 1927 [[Murder of Marion Parker|kidnapping and murder of Marion Parker]].
* "[[List_of_Dragnet_(radio_series)_episodes#1950_season|The Big Thank You]]" (Radio, 1950) – [[Louise Peete]]'s post-prison years and third murder, which led to her becoming the second of only four women to be executed in the California gas chamber.
* [[Dragnet_(franchise)#Dragnet_1966_(aired_1969)|1969 TV movie]] – The killing spree of serial killer [[Harvey Glatman]] in the late 1950s.<ref>{{cite book |first=M.
