A MAN has admitted murdering a well-known boxer and mixed martial arts fighter who was found seriously injured at a Blaenavon address.

Duane Keen, aged 47, was discovered with catastrophic injuries at a property on Riverside Drive in Blaenavon during the early hours of Thursday, October 17 last year. Despite the efforts of emergency services, he was pronounced dead at the scene.

Kai Pennell, aged 35, appeared before Cardiff Crown Court on Friday (Feb 6), where he pleaded guilty to murder.

He also admitted criminal damage relating to the destruction of a white Suzuki Swift belonging to Rebecca Phillips. A further allegation of making threats to kill will not proceed to trial.

Judge Tracey Lloyd-Clarke told the court that only a life sentence can be imposed for murder, with the minimum term to be decided at a later hearing. Pennell, of Riverside Drive, was remanded in custody and will return to court for sentencing on February 24.

Police were called to the address shortly after 2:00am. Witnesses reported armed officers, paramedics and an air ambulance attending, while the street was sealed off as forensic teams began their investigation.

In a statement, Gwent Police previously confirmed a major emergency response had been launched following reports of serious violence.

Family members paid tribute to Mr Keen, describing him as a dedicated sportsman and a loyal friend.

They said: “Duane was a talented boxer and MMA all-rounder with lots of belts to his name. He would help anyone who needed it and was always at the end of a phone.

“He loved being with his dogs and out walking with them. Duane will be greatly missed by all his family and friends. There are no words to express what we as a family are going through.

“Duane, you were a champ in the ring, but you were the biggest champ to us.”

The court heard that sentencing will take place later this month, when the judge will determine how long Pennell must serve before he can be considered for release.

Further details of the circumstances surrounding the killing are expected to be outlined at that hearing.

FIVE people have been arrested after a teenage boy died following an incident at a property in Abertridwr.

Officers from Gwent Police were called to Lower Francis Street at around 5:45pm on Thursday (Feb 5) following reports that a 17-year-old had suffered a serious injury.

Despite the efforts of emergency services, the teenager, who was from Abertridwr, was pronounced dead at the scene.

His family has been informed and is being supported by specialist officers.

Three men — aged 26 from London, 24 from Abertridwr and 18 from Cardiff — have been arrested on suspicion of murder.

Two women — aged 28 from Hereford and 24 from Senghenydd — were arrested on suspicion of assisting an offender.

All five remain in police custody while enquiries continue.

Detective Chief Inspector Jitka Tomkova-Griffiths said officers would maintain an increased presence in the area.

She said: “We understand that reports of this nature are concerning, and residents will see more officers locally while we continue our investigation.

“It is important that people do not speculate about the identities of those involved, as this could hinder our enquiries.

“If anyone has information, please speak to officers or contact us in the usual way.”

Anyone with information is asked to call 101 quoting log reference 2600038325, contact police via social media or the force website, or report anonymously to Crimestoppers on 0800 555 111.

A WEST WALES man accused of murdering his partner’s five-month-old son has told a jury he “panicked” and shook the baby in an attempt to revive him.

Thomas Morgan denies killing Jensen-Lee Dougal, who suffered catastrophic brain injuries at the family home in Clydach in March 2024.

The child was rushed to the University Hospital of Wales but died the following day in his mother’s arms.

Morgan, of Penyrheol Road, Gorseinon, is on trial at Swansea Crown Court charged with murder and three counts of inflicting grievous bodily harm with intent. He denies all charges.

Opening the defence case, the court heard Morgan claims the infant had been sick after feeding and was found choking and unresponsive when he returned with fresh clothes. He said he shook the baby, tapped his back and splashed water on him in an effort to get a reaction before seeking help from a neighbour. He told jurors he could not call an ambulance because his phone was faulty.

Asked in the witness box what he physically did, Morgan said: “I completely panicked. I shook him to get a reaction out of him.” He added he did not believe he used enough force to cause harm and said it was “absolutely not” his intention to hurt the child.

Prosecutors allege the injuries were inflicted deliberately.

The jury has heard detailed medical evidence describing bleeding and swelling to the brain, bleeding to the spine and eyes, bruising to the ears and chin, multiple rib fractures and fractures to the legs, elbow, spine and foot.

Doctors said some of the rib fractures showed healing, suggesting they occurred during two separate periods — between early January and early February, and again between mid-February and the end of March.

Consultant paediatrician Dr Deborah Stalker told the court each set of injuries was rare in babies and strongly associated with non-accidental trauma. Considering the total pattern, she said they were “purposefully inflicted”, consistent with abusive head trauma such as violent shaking.

“These injuries do not occur in the course of normal handling of a baby,” she said.

She added the brain damage was so severe that Jensen-Lee would have lost consciousness and gone into cardiac arrest within minutes. An equivalent accidental force, the court heard, would be comparable to a high-speed road collision or a fall from a second-floor window.

The prosecution claims Morgan was “fired up with anger” following an earlier argument when the injuries were caused. Morgan denies losing his temper or assaulting the child.

The trial continues.
