So you think you're a detective, huh? You've seen Law and Order, practically worship Sherlock, and can only clean your room while listening to Serial?

Well, now you get to prove how much of a sleuth you really are.

We know where the crime happened. We know how it happened. The question is...who did it.

Let's look at the last three people Maddie saw before she was murdered. Make sure to check each picture and GIF carefully for clues.

The last time Maddie saw her friend, Tess, they were grabbing drinks at the Layla Lounge. Tess let Maddie borrow the new lipstick she created after raving about how much money it made her.

But on the sly, Maddie stole Tess's lipstick. And Tess noticed.

Did Tess know that Maddie stole her lipstick with the intention of knocking it off for her own line? Was this enough to fuel murderous intentions?

Next, we have Maddie's roommate, Morgan. As Maddie was taking selfies, Morgan walked in and asked for the rent.

Frustrated at Maddie's irresponsibility and cruelty, Morgan retreated to her room. Was she plotting revenge?

The last time Maddie and her boyfriend, Regan, were together, the night started off sweet. He gave her a black choker, and she told him that she loved it.

Then things quickly turned sour. When Maddie reached to check her phone for vlog comments, Regan felt like he was being ignored and an argument ensued.

After the argument, Regan stepped outside to vent his anger. Did this lovers' spat lead to Maddie's untimely death?
