In March 2015, Cheyenne Rose Antoine posted a selfie with her BFF Brittney Gargol. It later became the key piece of evidence in her murder conviction.

Almost three years after the strangulation death of 18-year-old Gargol in the Canadian town of Saskatoon in Saskatchewan, Antoine was arrested and charged with second-degree murder, but the 21-year-old ended up pleading guilty to a lesser charge of manslaughter. The belt she was wearing in the selfie — which had been shared on Facebook just six hours before Gargol’s body was discovered — matches the one found near her friend. Authorities determined the accessory was used as the murder weapon, according to The Saskatoon StarPhoenix.

The teen’s body was found dumped by the side of the road on March 25, 2015. Antoine had attempted to cover her tracks by writing, “Where are you? Haven’t heard from you. Hope you made it home safe,” on Gargol’s Facebook page after the two spent the previous night together.

Antoine initially told police that the pair had been out drinking, but that she had gone home with an unidentified man, and didn’t know what happened to her friend. Officers later received a tip that the brunette had drunkenly confessed to the killing.

In court, Antoine admitted the duo got into an argument, but claimed she doesn’t remember murdering Gargol. She was sentenced to seven years in prison after entering her guilty plea. “I will never forgive myself,” Antoine said in a statement read aloud by her defense lawyer, Lisa Watson, in court. “Nothing I say or do will ever bring her back. I am very, very sorry…It shouldn’t have ever happened.” Watson added, “She knows the family would like an explanation, a reason, but unfortunately she can’t provide that.”

After sentencing Antoine, Judge Marilyn Gray told her, “Honor your friend by becoming a positive member of the community. You owe it to her.”
