A talented male model and musician with a bright future ahead of him was found hanged in his bedroom by his mother, an inquest heard today.

Sean Semmens from Prestwood, who had walked the catwalk in Italy and New York for designer brands including Diesel, died just two months after his 21st birthday.

His mother Alison returned home from work and went upstairs at the address in Widmere Field to speak to Sean after finding the kitchen in a mess.

When she saw him hanging from an air vent in his room, she screamed to a neighbour for help and they cut his him down. However, paramedics were unable to save him.

The promising model was signed to Supa Model Management in London and played guitar with his band, Coastal Cities.

In an interview a year before his death, he described his heroes as guitarist John Frusciante and rapper Eminem.

An inquest in Beaconsfield heard that Sean's mother called emergency services after making the horrifying discovery.

Detective Constable Robert Gibson, of Thames Valley Police, said: "Police were contacted at 5.07pm on February 17 with reports of a 21-year-old male found hanging at his home.

"Neighbours helped cut him down and they commenced CPR but ambulance crews estimated he died around three to four hours prior to their arrival.

"Sean had a history of mental health issues, self harm and suicidal thoughts and attempts which were documented by police."

The inquest heard he had contacted officers saying he wanted to kill himself in 2010 and stood on train tracks a year later, threatening to jump in front of a train.

Detective Constable Gibson said: "No note was located and the phone in his bedroom was locked with a PIN. The snapshot of messages on his phone included communications to do with an ex-girlfriend."

His mother Alison told the inquest: "We feel he was doing well the night before and his ex-girlfriend thinks he might have taken something that morning. Is there any suggestion he might have taken a legal high?"

A toxicology report only revealed the medications he was taking for depression and Buckinghamshire Coroner Richard Hulett said: "Legal highs prove very problematic for toxicology and they are almost inventing a new one every week.

"They looked for it and it was not there."

Recording a narrative verdict, the coroner added: "He had a history of self-harm but a lot of that is people making records of him suggesting he is going to do something rather than actually doing something, which is rather different.

"He died in the way he did but his intentions and motivations are not revealed by the evidence. I have to be able to say beyond reasonable doubt that he meant to carry it through.

"I have had cases where people just want to make a point and become suspended and die very quickly."

The former Amersham and Wycombe College student, who lived in Prestwood, described himself as "observing, sensitive, unpredictable and mysterious" in an interview.

A tribute from his Supa Model Management posted after his death read: "Sean was a kind-hearted, gracious and humble individual who touched the lives of so many people he met.

"He was an amazing model, great musician and also a wonderful friend and relative to so many. His gentle spirit will be greatly missed by the SUPA team and our thoughts and love is with his family and friends."
