Template:QOTW-Quillsville Cold Case/Connection to Cold Case
Like in Cold Case, the detectives interviewed witnesses associated with the crime and piece together the story of what led the victims to their death. These interviews were accompanied by flashback sequences to the time of the murder which dramatized the testimony. Witness testimony, even from people who would later be revealed as the killer, was almost never false. At most the guilty party would lie by omission, leaving out critical details, or stopping their narrative before they implicated themselves. The witness testimony was also generally presented in chronological order so that it formed a cohesive linear story for the audience.
Unlike Cold Case, the episode distinguished by "double casting" in which the characters and witnesses would flash back and forth in the scene representing them as they looked at the time of the crime and in the present day. This was done with different voice actors as children or much younger selves especially if the year in question was well in the past. If it was judged that the character was not likely to have altered in appearance significantly except for weight and gray hair, the same actor would be used. This was not just with the guest actors themselves but sometimes with the detectives as well if they had any involvement in the original investigation. For example, Ava Willis flashed back and forth from 2009 (post-Ava's Makeover) to 2002 ("Pilot") and 1996 (as a male, voiced by Frank Davidson).
