(CNN)On the evening of March 24, 2015, Cheyenne Antoine and Brittney Gargol posed for a selfie and posted it on Facebook before heading out for the night.

Within hours, 18-year-old Gargol was dead, her body found lying on the side of a road in Saskatchewan, Canada.

Nearly two years later Antoine, now 21, confessed to the murder after police identified the belt she used to strangle and kill Gargol.

It was the same belt Antoine was seen wearing in that photograph on the last night of her friend's life.

"She told police they went out drinking and met up with a white male," Ritter said. Afterward, Antoine said she went to her uncle's.

However, when Saskatoon Police talked to Antoine's uncle, the story fell apart.

There was no white male to speak of, and Antoine's uncle eventually admitted to police that Antoine had asked him to lie for her and say "two black men" killed Gargol.

Don’t murder your best friend. Can we agree there? Now’s just not the time. The world’s in rough shape, and the nation of Britain is trying to ban the very idea of friendship, so now’s a great moment to lock in and enjoy each other’s company. Now, if you are going to murder your best friend, you’ve got to make sure you’re not wearing the murder weapon in any photos. 

You’d think this would be pretty self-explanatory but I guess not. Seems like this was basically the perfect crime with the exception of the one thread that UNRAVELED IT ALL. We had the uncle lying, we had a couple mysterious dudes to take the fall, and of course, nobody was going to suspect the best friend: all until this bougie-ass belt showed up in a photo from the night of the murder. If you’re a murderer, you’ve got to make sure these photos don’t exist, or maybe that’s suspicious too. I don’t know, this is why I don’t murder people. I would at least throw the belt out, but MAYBE THAT’S SUSPICIOUS TOO. This is why I’m not a murderer!
