On Monday during a court appearance, a 21-year-old Canadian woman named Cheyenne Rose Antoine claimed responsibility for killing her best friend, Brittany Gargol, after a night of partying and drinking back in 2015. Antoine says that she doesn't remember actually killing Gargol on that particular night but, nonetheless, she confessed.

A passerby had seen the 18-year-old Gargol strangled to death on the side of the road in 2015. As a result, Antoine had been arrested when authorities learned that the two friends had taken a selfie just hours before her body was discovered. In that selfie, Antoine was wearing a belt that matched one found next to Gargol's body. Authorities believe that belt was the murder weapon.

In addition, Antoine posted a lengthy message that wondered about Gargol's whereabouts on the night of her death. Authorities believe that this was Antoine's attempt to throw them off her trail. According to reports, Antoine also lied to police by telling them that she was with a different friend on that night, before going home to meet up with her uncle. On top of that, she claims that Gargol had left to hang out with an unidentified man following a night of barhopping.

While wearing the same belt that was found next to her dead friend was a pretty big smoking gun, police were already put onto Antoine's trail after one of her friends told police that she had drunkenly confessed to killing Gargol after they got into an argument—which would also seem to be an even bigger smoking gun). 

On Monday Antoine confessed to a lesser charge of manslaughter after she was initially arrested and charged with second-degree murder. For her crime, she was sentenced to seven years in prison. Additionally, at her Monday court appearance, she stated that she could not remember what the argument was that caused her violent outburst. She also apologized via a statement where she said, in part, "I will never forgive myself. Nothing I say or do will ever bring her back. I am very, very sorry... It shouldn’t have ever happened."
