Lore (you may skip below the image if you are looking for the rules):

After the successful completion of your previous mission, you've been promoted to a detective sergeant. Your next case is in a big town roughly an hour away from the capital. Numerous people have been reported missing in a span of few days in the area. Your mission is to find out what happened in this town.

This puzzle is part of a series called "Lost and Found" in which modifications to the killer variant will be explored in the context of a detective training lore. You can find links for the rest of series below;

• #1: Rogues Gallery
• #2: Innocence is Illegal
• #3: Innocence is Legal
• #4: Onion Rings
• #5: Lost Village
• #7: Lost City
• #8: 4 Stones, 1 Bird

Rules:

Normal Sudoku rules apply: Place the digits 1-9 in every row, column and 3x3 box once each.

Kropki: Digits separated by a white dot must be consecutive. Digits separated by a black dot must be in a 1:2 ratio.

Ambiguous Cages: There are 4 types of cages in this puzzle all of which appear at least once. Digits in a cage, regardless of its type, can't repeat. Which cage is which type must be deduced by the solver. Every cage is denoted by a letter. Alphabetically consecutive cages can't be of the same type.

• Killer Cages: Digits in a killer cage sum to the value given in the top left corner.
• Suspect Cages: The sum of the digits in a suspect cage must be 1 away from the value given in the top left corner.
• Framed Cages: The sum of the digits in a framed cage must be 2 away from the value given in the top left corner.
• Innocent Cages: The sum of the digits in an innocent cage must be at least 10 away from the value given in the top left corner.

Victims: For every killer cage in this puzzle, there must be at least one innocent cage on the grid (the victim).
Fog: The grid is covered by fog. The tracker on the top left corner is used to track which cage belongs to which type. Fill in that tracker by using the digits 1-4. 1 for Suspect, 2 for Framed, 3 for Killer, and 4 for Innocent cages. Correctly identifying cages in the tracker will gradually uncover the fog (This does not necessarily mean that every single correct digit placed in the tracker will always uncover some of the fog).
