A human foot discovered almost 20 years ago has been identified as that of a missing Lancaster University student.

Graham Maxwell Rogers, who had a history of depression, was living with his parents at Wotton-under-Edge, Gloucestershire, when he went missing on April 10, 1993, aged 26.

The environmental science student had left his parents’ house, saying he was going to Stroud.

However, on April 19 his car was found in Chepstow, a short distance from the Rivers Wye and Severn.

On November 7 that year the remains of a human foot were found in a Reebok trainer in flood defences on the River Severn.

Forensic DNA testing was carried out on the foot in 1994 but was unable to identify who it was.

However, advancements in DNA testing techniques led to it being resubmitted by police in December last year and a match was obtained.

Mr Rogers’ identity was confirmed after DNA tests were carried out comparing the body part with his next of kin.

An inquest at Gloucester Coroners Court said the development in technology showed it was one billion times more likely to be Mr Rogers’ foot than anybody else’s.

Deputy assistant coroner Katie Skerrett recorded an open verdict and the cause of death as unascertained.
