To figure out whose bag it is, read the yearbook.

The yearbook says Harrison was the captain of the basketball team. The bag is Harrison's. Can you find any clues about what Harrison might use for a 3 number password?

There is a printout of "SecureLogix Security Questions" for Harrison (from Part 2). One of the account recovery questions has a 3 digit answer format (Harrison's lucky day).

To figure out Harrison's lucky day, read the yearbook carefully (the yearbook is Harrison's).

Pay special attention to the autographs page.

One of the autographs mentions that Harrison won 10k on a scratch ticket in grade 10 on April Fool's day.

Harrison graduated in 2002, so Harrison would have been in grade 10 from 1999-2000. Harrison's lucky day is April 1st, 2000. Translated into dmy format, this becomes: 140. The password to open the basketball bag is 140.

Look at the "Shadows Over Millfield" review carefully.

Read the police interviews carefully.

Dante says (in his police interview) that he was watching "Shadows Over Millfield" the morning Summer was found (September 14th, 2019).

Does the Shadows Over Millfield review say when the movie starts showing in theaters?

The "Shadows Over Millfield" review says the movie comes to theaters "this sunday". The review is dated September 10th, 2019. "This sunday" refers to September 15th, 2019. In Dante's police interview, he says he saw Shadows Over Millfield the morning of September 14th, 2019. Dante lied to police about his whereabouts on September 14th.

The Ghost Lock Messages are between Summer and "DM". The key is to figure out who "DM" is.

The messages are sent on September 13th, 2019, and they reference meeting up "tomorrow" (September 14th). Look at Summer's billing records and patient schedule to see what her schedule was for September 14th.

Summer's schedule says she was supposed to be seeing "Damien Maiden" at 10:30AM on September 14th. Summer also saw Damien the previous Saturday (7th). But Damien is not in Summer's billing records. Under "Appointment Code", Damien is classified as "NS" (Not Specified).

Assuming the records are correct, why would Summer want to see a patient but not bill them? Summer can bill patients for $0 (Pro Bono Appointments are $0), so the reason can't be that Summer is just trying to help Damien out by seeing them for free.

Summer is hiding the fact that she's seeing Damien. She either doesn't want to leave a paper trail with her billing records, or she doesn't have a patient named Damien (and doesn't want to falsify billing records.)

Does Summer have any sorts of relationships she would want to hide?

Did you figure out who the scrunchie (from Part 2) belongs to? If not, look at the business card (from Part 2).

If you already figured out who the scrunchie belongs to, don't count this hint.

The scrunchie is Medina's. The business card links to a website (www.eatnuvo.com). On the website, there's a picture of Medina wearing the scrunchie.

Did you figure out the significance of the blue die inside the scrunchie (if you haven't found this, try unzipping the scrunchie and you'll find the blue die inside)? If you haven't, read Summer's blog post "First Date" carefully.

If you already knew who the scrunchie belonged to and the significance of the blue die, don't count this hint.

The blue die is a "souvenir" Medina took home from her date with Summer. Summer and Medina are dating.

If you already knew about the significance of the blue die, don't count this hint.

Summer is married, and she's having an affair (with Medina). This is a relationship Summer wants to hide. Medina is "DM" (from the Ghost Lock Messages).

If "DM" is Medina, then who is "G"? Medina (as DM) texts Summer and says "G is getting suspicious. I know you're ready to cut the cord with H". "H" is Harrison, Summer's husband.

If you don't know who G could be, have a close look at the website listed on Medina's business card (www.eatnuvo.com)

"G" is Gerry, Medina's husband.

On the Nuvo website (www.eatnuvo.com), the "About Us" section reveals that Medina and Gerry are married. In the Ghost Lock Messages, Medina tells Summer she isn't ready to tell "G", aka Gerry, her husband, about her and Summer yet.

"H" is Harrison, Summer's husband.

"DM" is Medina.

This note was found in an envelope (labelled Evidence #844B) that contained ripped up/shredded pieces of an office layout. This layout is important. Try and put it back together (like a puzzle).

In the upper left hand corner of the note, there is a 3x3 grid. This grid is composed of 9 squares.

The note contains 9 letter combinations: "OA", "OB", "OC", "B", "K", "R", "H", "S", "E".

The 9 letter combinations ("OA", "B" etc.) are related to the office layout.

The office layout (when it's put together), has 9 labelled areas: "Office A", "Office B", "Office C", "Bathroom", "Kitchen" etc.) Each of these correspond to one of the 9 letter combinations.

To solve this puzzle, you need to fill out two 3x3 grids. One grid is the alphabet. It looks like this:

[ABC] [DEF] [GHI]

[JKL] [MNO] [PQR]

[STU] [VWX] [YZ]

The second grid is based on the office layout.

The office layout has 9 areas (Office A, Office B etc.) Each area can be represented by its initial[s]. The 9 areas become: "OA" (Office A), "OB" (Office B), "OC" (Office C), "B" (Bathroom), "K" (Kitchen), "R" (Reception), "H" (Hallway), "S" (Storage), "E" (Entrance).

These 9 areas need to be written in a 3x3 grid. To figure out how to place them in the grid, look at where the areas are (relative to each other) in the office layout.

The 9 letter combinations can be written in the 3x3 grid based on where they are in the office layout. For example, the "Storage" room (which corresponds to "S") is located in the upper left hand corner of the office layout. So, "S" should go in the first square of the 3x3 grid. Once the 3x3 grid is filled in, it should look like this:

[S] [K] [B]

[OA] [H] [OC]

[OB] [E] [R]

The note is written using 9 symbols. Each symbol is represented by one or two uppercase letters (OA, OB, OC, B, E, H, K, R, S). The symbols are the same as the initial[s] of the 9 labelled areas in the office layout.

Each symbol is differentiated in one of three ways:

1) there are 2 horizontal lines above and below the symbol

2) there are 2 horizontal lines above and below the symbol and a vertical line to the left of the symbol

3) there are 2 horizontal lines above and below the symbol and a vertical line to the right of the symbol

Because each symbol can be written in 3 different ways, there are 27 unique symbols (9*3=27).

Use the two grids (see hints 3 and 5) to translate the unique symbols into alphabetical letters. The grids are depicted below.

Alphabet Grid:

[ABC] [DEF] [GHI]

[JKL] [MNO] [PQR]

[STU] [VWX] [YZ]

Office Layout Grid:

[S] [K] [B]

[OA] [H] [OC]

[OB] [E] [R]

Each unique symbol can be translated into an alphabetical letter using the alphabet grid and the office layout grid. The note is written using symbols from the office layout grid.

Here are the grids:

Alphabet Grid:

[ABC] [DEF] [GHI]

[JKL] [MNO] [PQR]

[STU] [VWX] [YZ]

Office Layout Grid:

[S] [K] [B]

[OA] [H] [OC]

[OB] [E] [R]

Each grid has 9 squares. The positions of these squares can be labelled as follows:

[1] [2] [3]

[4] [5] [6]

[7] [8] [9]

There are two steps to decoding the unique symbols. The first step is to match the symbol to its corresponding position in the alphabet grid. For example, symbol "K" can be matched to square 2 in the alphabet grid ([DEF]). Another example: symbol "OB" can be matched to square 7 in the alphabet grid ([STU]).

The next step is to translate the symbol into one of the three letters in the alphabet grid. For symbol "K", this would mean translating "K" into d, e, or f.

Hint 6 explains how each symbol is differentiated in one of three ways. Each symbol has either a vertical line to the left of it, a vertical line to the right of it, or no vertical lines at all. All symbols have horizontal lines above and below the symbol. These 3 differentiations determine which alphabetical letter the symbol should be translated into.

Each symbol is differentiated in one of three ways (2 horizontal lines + 1 vertical line to the left of the symbol, 2 horizontal lines + 1 vertical line to the right of the symbol, 2 horizontal lines + no vertical lines). These differentiations are based on where letters are located within their square in the alphabet grid.

The first differentiation (2 horizontal lines + 1 vertical line to the left of the symbol) means the letter is located in the left part of their square. For example, the first 2 squares in the alphabet grid are: [ABC] and [DEF]. A and D are located in the left parts of their respective squares.

The second differentiation (2 horizontal lines + 1 vertical line to the right of the symbol) means the letter is located in the right part of their square. For example, the first 2 squares in the alphabet grid are: [ABC] and [DEF]. C and F are located in the right parts of their respective squares.

The third differentiation (2 horizontal lines + no vertical lines) means the letter is located in the middle part of their square. For example, the first 2 squares in the alphabet grid are: [ABC] and [DEF]. B and E are located in the middle of their respective squares.

We can translate each unique symbol into an alphabetical letter by: 1) matching it to its corresponding square in the alphabet grid (based on the locations of the 9 squares in each grid); 2) translating the symbol into one of the three letters in that alphabet square based on how the symbol is differentiated.
