A smiling selfie has helped to convict a Canadian woman of killing her friend after the police noticed that the murder weapon was visible in the image.
On Monday, Gargol's friend Cheyenne Rose Antoine, 21, pleaded guilty to manslaughter in Saskatoon Provincial Court in connection with the death. Antoine was wearing the same belt in the photo found near the crime scene.

"Where are you? Haven't heard from you. Hope you made it home safe" on Brittney's Facebook page the morning after her death, which police soon realised was an attempt at diverting attention away from herself.
This put her on the radar of investigators, who found the selfie, and eventually arrested her a year ago. Antoine accepted responsibility for strangling Gargol after getting into an argument with her during a night of drinking but said she did not remember the incident. "I will never forgive myself".
"It's quite remarkable how the police developed this information", Crown prosecutor Robin Ritter told the CBC.
She "has issues ... and because of those issues, she is risky", the CBC reported.
Friends said Gargol was attending Nutana Collegiate and was working at Vern's Pizza and the German Cultural Centre at the time of her death.
A selfie shared to Facebook, posted hours before Gargol's body was found, showed Antoine wearing a belt which matched the same belt that was discovered near Gargol's body.
She revealed that she had hit Gargol and strangled her during their altercation. Northing I say or do will ever bring her back.
Before Antoine was sentenced, Gargol's aunt gave a victim impact statement to the court.
"I am very, very sorry.It shouldn't have ever happened".
Antoine pled guilty to Gargol's murder Monday, and received a seven-year sentence for manslaughter.
