For a list of the rewards obtained during the additional
investigations, go to Additional Investigation/Rewards
Additional Investigation is the post-indictment chapter (or also known as chapter 4) of every case that you will help the suspects that were proven innocent for said cases and obtain some rewards along the way.
Premise[]
In every single case after the killer is arrested, with the exception of the first case in Grimsborough, titled The Death of Rose Wolf, you MUST complete the final chapter of the case called additional investigation to unlock the next case.
In this chapter, the player must check up on some of the characters who were suspected, but turned out to be innocent. The tasks range from helping out innocent suspects who are in need of something, get more information about the most suspicious, or even catching post-murder findings (such as drug dealings).
In some circumstances, there will be innocent suspects who the player will have to help by examining an item before investigating a crime scene. The player MUST examine the item before investigating a scene where their help is required. Sometimes the innocent suspect already has something in mind and will tell the player a list of tasks he/she need help on, so the player will only be able to investigate, examine, analyze (if necessasry), and report back to the innocent suspect.
For Grimsborough, only one suspect needs to be spoken to in the first case titled "The Death of Rosa Wolf". Two suspects will need to be spoken to in the cases of Corpse in a Garden, It All Ends Here, A Brave New World, and There Will Be Blood, but in the latter case one suspect will have to be dealt with one at a time. Starting with the case The Grim Butcher and continuing till the case of Snakes on the Stage will have three suspects whom the player will need to talk to for the tasks aforementioned. For the cases Burying the Hatchet and Ashes to Ashes, there will be three innocent suspects to be checked up on, but one of them can't be checked up on until the other two are checked up on first. In the case The Poisoned Truth, there will be two legs - one with the killer and the innocent suspect, and the other with just the innocent suspect.
For Pacific Bay, there's no telling how many suspects will need to be checked up on and/or which ones will reward the player and/or after they player gained more information about them. There will be cases in which all of the innocent suspects will be checked up on, but only two will give rewards to the player, while others will have three innocent suspects will give the player rewards.
Be aware in certain circumstances, based on the canon's direction, you may be required to interrogate killers during the Additional Investigation. As of World Edition, you may also be required to talk to a person who was not a murder suspect (quasi-suspect) in the Additional Investigation. These quasi-suspects may also be the ones to give rewards to the player.

Plot Continuity[]
In just about all Grimsborough cases and some Pacific Bay cases, the Additional Investigation is unnecessary to the development of the game's story for the most part. Starting from the sixth district of Pacific Bay, however, the Additional Investigation chapters have been named differently in an effort to ensure that all chapters of each case are tied-in with the game's story and its related canon.
