Police officially drop murder investigation after man died two years ago

Tyron Jonsyn, 28, was found unresponsive at around 11pm at a house in Lock Court, on the Brize Meadow estate between Brize Norton and Carterton on Monday, January 16 2023.
At the time of Mr Jonsyn’s death two men were arrested on suspicion of murder, but since then the case has been dropped as the Crown Prosecution Service (CPS) said there was not enough evidence of criminal activity.
Therefore, the two men arrested have been released with no further action to be taken.
An inquest was held into the 28-year-old’s death at Oxford Coroner’s Court on Monday, January 27.

“The investigation was long and protracted, and I would like to pay tribute to Tyron’s family for the patience and dignity that they have shown throughout.
“We sought advice from the CPS, who ascertained there was insufficient evidence to support a murder charge.
“The conclusion from the inquest was that the cause of Tyron’s death was unascertained.

“As such, our investigation has been filed, pending any further future information coming to light.
“I know that Tyron’s loved ones will struggle to come to terms with his untimely passing, and not having the knowledge of how he died.
On behalf of all of us at Thames Valley Police, my thoughts remain with them as they look to move on with their lives.”
The inquest heard Mr Jonsyn, of Hilton Avenue, Aylesbury, attended an address when an ‘altercation’ ensued with reports of a stabbing and strangulation.
However, when Mr Jonsyn’s body was examined by Home Office pathologist Dr Brett Lockyer, he found no evidence of either.
Dr Lockyer said the cause of death was ‘unascertained’.
He added: “It’s more likely than not that he died from cardiac arrhythmia.”
Area coroner Nicholas Graham gave a narrative conclusion, agreeing with Dr Lockyer’s theory.
He gave his condolences to Mr Jonsyn’s family.
After Mr Jonsyn died, police released a tribute from his family.
It said: “Tyron brought joy, kindness and endless love to our family.
“He was a bright light that lit up our lives.
“Tyron was unique, kind, loyal and irreplaceable. He has left his many friends and family so many special memories that we shall treasure.
“We will miss him forever.”
