Jordan Easton died trying to demonstrate his stab-proof vest worked.

Five days after his 22nd birthday, Jordan Easton was celebrating with friends at a house in north-east England when he began talking about the vest he was wearing. It was stab-proof, Easton allegedly announced. He offered a demonstration.

But the vest was not stab-proof.

"While in the kitchen, he took hold of a knife to demonstrate it was stab-proof and sadly realised it wasn't the case," Teesside assistant coroner Karin Welsh said at a recent inquest into the August 23, 2017 incident, the Teesside Gazette reported on Saturday.

Easton died from the self-inflicted knife wound. Although his death was originally reported in the local media, the details of how the young man met his end were revealed only at the inquest held at the Teesside Coroners' Court.
