Jay Slater, a 19-year-old from Oswaldtwistle, Lancashire, disappeared after attending the NRG music festival in Tenerife last June. In previously unseen videos, he is seen bragging about stealing a £12,000 watch and appears to be under the influence of drugs while with a convicted drug dealer before going missing. His remains were found 29 days later near Masca, and his disappearance sparked widespread speculation on social media about possible criminal involvement.
