Look at the "Shadows Over Millfield" poster carefully.

Reread the witness statements and police interviews.

Read Dante's interview carefully.

Dante says (in his police interview) that he was watching "Shadows Over Millfield" the morning Summer was murdered.

The "Shadows Over Millfield" poster says the movie comes out in theaters on September 15th. Summer was murdered on the 14th. Dante lied about his alibi.

Check Summer's patient schedule and billing records — there's a discrepancy between the two.

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.)

Also... Damien Maiden is an odd name, isn't it?

Have another look at the blue die, the police note (the note that starts off with "I spoke to the 911 caller"), the orange pawn, Summer's blog entries, and the officer notebook.

The 911 caller, told police she heard a scream, ran inside the building, and found Summer. If we look at the officer notebook, though, we see that no other witnesses heard a scream... odd.

The 911 caller also told police she didn't know Summer, but the officer said she was very distraught... also odd.

Summer's blog entry titled "First date" has a picture of a board game. In the picture, there's a blue sparkly die and an orange pawn. Summer mentions she (and the woman she was on a date with), took "souvenirs" from their date.

The loose officer note mentions that the 911 caller dropped a blue sparkly die. Medina is the 911 caller, so Medina must have dropped the die, which means Medina was on the date with Summer. Judging by Summer's blog posts, Summer and Medina are seeing each other, and Summer is infatuated with Medina.

Summer was going to meet with Medina at 10:30AM. Medina and Summer are having an affair. Summer mentions having met an amazing woman in her blog. Summer also disparages her husband, Harrison, in her blog. Summer also has a pride pin, which is consistent with her interest in Medina.

Although we only have Summer's billings records from the past 2 weeks, it seems like Summer meets "Damien" on Saturdays at 10:30AM. By putting a fake appointment in her calendar, Summer has an easy excuse for why she's gone on Saturday mornings. If Harrison snoops through Summer's calendar, she's in the clear.

Medina's behaviour is another clue. Medina was shifty when speaking with the police at the scene - she refused to give them her name, and she left extremely quickly. She says she heard a scream from the street, but this doesn't add up because the two other witnesses (who were right outside Summer's office) didn't hear anything.

Medina also lied and told police she didn't know Summer (which we know isn't true - Summer has a note from her - the note in the luggage tag matches the handwriting on Medina's police statement).

Medina is likely lying because she's married (which we know from the website www.nuvoseattle.com - it says Medina and her husband own a restaurant together). Medina wasn't walking down the street when she heard a scream. She either murdered Summmer (and then called 911) or discovered Summer's body and then called 911. Either way, Medina doesn't want police snooping around and figuring out that her and Summer were having an affair. It will make her look suspicious, and if her husband finds out, it could ruin her marriage.

Note that we don't know if Medina lied about her alibi (but we know she lied about not knowing Summer), because she may have been walking down Yonge Street (what she says in her police statement) before she went in to Summer's office (and either killed Summer and called 911, or found Summer dead and called 911).

The final clue (that tells us Summer was meeting with Medina at 10:30AM) is the name "Damien Maiden". "Damien" and "Maiden" are both anagrams for Medina.

This checkpoint is to decode/decrypt the note inside the basketball bag (Written on a paper titled: "Chapter 6: The Brain").

The note says "Remember when you were afraid to lose me." Two of these words are highlighted/emphasized. Pay special attention to those words.

Also - if you're unfamiliar with decrypting notes, see the "Puzzles" page of the yearbook.

Can you connect those words to the brain diagram?

If you need help connecting the words, read the infographic on panic attacks carefully.

The two words that are underlined are "Remember" and "Afraid". Each of these words is related to a part of the brain.

As mentioned in the panic attack infographic, memory is associated with the hippocampus, and fear is associated with the amygdala.

Can you find these two parts of the brain on the brain diagram? Can you connect this to one of the ciphers mentioned in the yearbook puzzles page?

The hippocampus is number 6 on the brain diagram and the amygdala is number 11.

The hippocampus is number 6 on the brain diagram and the amygdala is number 11.

To apply the Ceasar cipher, shift every first letter by 6 and every 2nd number by 11.

Decrypted, the note reads: "I thought you knew better."

This note was found in an envelope (labelled Evidence #844B) that contained ripped up/shredded pieces of a floor plan/office layout. This floor plan/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 is an important clue.

The note contains 9 letter combinations: "OA", "OB", "OC", "B", "K", "R", "H", "S", "E". There are 9 spots in the 3x3 grid.

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

The office floor plan (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.

The alphabet can be written in a 3x3 grid, with each square containing 3 letters (and the 9th square having two letters - Y and Z). Think of a phone key pad - you have [ABC] on one key/button, then [DEF] on another key/button, then [GHI] etc. The note here has been encrypted using this logic.

There are 9 letter combinations ("OA", "OB" etc.) and 9 squares in the 3x3 grid. Each letter combination corresponds to one square on the grid. To figure out which letters corresponds to which square, look at where the letters combinations are on the office floor plan . First, you'll need to match each letter combination to an area/room on the floor plan (e.g. "OA" can be matched to "Office A", and "K" can be matched to "Kitchen"). Write out the 9 letter combinations in the 3x3 grid according to where they are on the floor plan.

The 9 letter combinations can be written in the 3x3 grid based on where they are on the floor plan. 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]

[S] represents [ABC], [K] represents [DEF], [B] represents [GHI], [OA] represents [JKL], [H] represents [MNO], [OC] represents [PQR], [OB] represents [STU], [E] represents [VWX], and [R] represents [YZ].

Next, you need to figure out how the 3 letters (for example, the ABC in the [S] square) are being differentiated. Look at the note and notice how one letter combination (for example, "OA") is written in different ways. Each letter combination (like OA, K etc.) can be written in 3 ways - each way represents a different letter. For example, [S] can be written 3 ways - if S is written in the first way, it represents A, if S is written in the second way it represents B, if it's written in the third way, it represents C.

Each letter combination can be written 3 ways. The 3 ways depend on the physical location of the letter in the square. For example, we know [S] represents [ABC]. A is the first letter in the square, B is the second, C is the third. Similarly, [K] represents [DEF], D is the first letter, E is the second, F is the third. All "first" letters are differentiated in the same way, as are all second letters and all third letters (i.e. all "first" letters have something in common, all "second" letters have something in common, and all "third" letters have something in common).

In the note, there are 9 letter combinations (e.g. B, K, OA etc.). Each letter combination has a "symbol" drawn around it. The symbol either looks like an "L", a backwards "L" (i.e. the bottom part of the L points to the left instead of the right, like this: "_|"), or like this: "|_|".

As explained in the previous hint, there are 3 symbols ("L", "_|", "|_|"). The symbol corresponds to the letter's position (e.g. first letters, like A or D, all have the same symbol, second letters, like B or E have the same symbol, and third letters have the same symbol). The symbol represents the letter's position. "First" letters are represented by the "L" symbol (because they are in the leftmost position in the square, the "L" represents them being beside the left wall/border. "Third" letters are represented by the backwards L (i.e: _|) because they are in the rightmost position (and so they have a right wall/border). "Second" letters are the middle letters, so they are depicted by this symbol: "|_|" (since they aren't on the left or right, both walls/borders are shown).

The letter can be decrypted as follows:
