Teenager Thomas Jones went missing on a night out with friends during his first week at university in Worcester. His body was recovered from the River Severn more than a week later. 5 Live Investigates has been told that Thomas's death and dozens more like it could have been prevented - if only certain safety measures were put in place. 150 young men have died after going missing on a night out over the last nine years. 5 Live Investigates has seen new research which reveals between 10 and 20 men die every year after going missing in towns and cities across the UK – the majority of them under the age of 35. Practical safety measures like late night transport to get people home, improved lighting and barriers between footpaths and waterways could all help prevent similar tragedies in the future, according to campaigners and charities.
