[1] An aspiring architect and engineer, Jermaine Goupall who was also known as “Jetz” was a 15-year-old student at St. Joseph's College and attended Saturday school at Croydon Supplementary Education Project.

[2] During the summer holidays, after an evening with friends at a cinema, the group was ambushed by masked youths of the CR0 gang armed with knives in the Thornton Heath area of London.

Four out of the five youths were convicted on 14 February 2018, resulting in three of the offenders – Adam Benzahi, Samuel Oliver-Rowland and Junior Simpson – being sentenced to a total of 72 years for premeditated murder.

On the first day of the trial, the court was told that Saskia Haye-Elliot – another female youth charged for the murder – said she thought the group were only going to "annoy or irate" members of the CR7 gang by taking videos of them to post on Snapchat and YouTube.

Extensive details about what happened to Jermaine that fatal night were highlighted in court, bringing to light that the offenders were looking for anyone they believed to be in the opposing gang.

After Jermaine's trial, Director of Public Prosecutions Max Hill stated that "violent social media posts must be used by prosecutors to crack down on gangs.
