A jury's found a man guilty for the murder of a teenager in the county, back in 2024.
19 year old Kalvin Taylor was killed in Norwich.
Officers were called after reports a man’s body had been left at a flat in Lefroy Road, Mile Cross.
A post-mortem found that Kalvin had died from a single stab wound to the chest, when he was discovered on a sofa at a flat on Lefroy Road in late September, of that year.
This was almost a week after he sustained a fatal stab wound to the chest with a Rambo-style knife on the afternoon of Sunday September 15 2024.
20 year old, Leon Bangura of Old Kent Road, London and three others were subsequently charged with his murder.
Two men were also charged in relation to this, but later released with no further action.
Leon Bangura was also charged with two counts of being concerned in the supply of Class A drugs, possession with intent to supply, and possession of a bladed article in a public place.
Bangura was arrested in a parked car in Norwich in possession of a knife.
What happened:
During police interviews, Bangura and Hall answered no comment to all questions and Dugdale lied to police for over two hours before providing a more accurate account. All were charged with murder and remanded into custody.
Kalvin was believed to have been working for the 'Batman' drugs line while Bangura worked for the rival ‘Lenny’ line. The court heard that Kalvin had been staying at the Lefroy Road flat where a man and woman, witnesses who are not named, were the tenants. Kalvin had been dealing drugs from the flat.
Giving evidence at court, the male tenant said that Adam Dugdale, who was known to him, rang him at the Lefroy Road flat to arrange to come to the address. Instead, Dugdale, Carrie-Anne Hall and Leon Bangura all turned up at around 1pm and, as the tenant opened the door, they all rushed in.
Hall tried to push the tenant into the bedroom, telling him, ‘This is nothing to do with you.’ The tenant then pushed past Hall into the lounge and saw Kalvin pull out a ball of drug wraps, the size of a small football, thought to be worth about £5,000.
One of the men shouted, ‘Where's the money?’ and Kalvin pointed over to his jacket on the sofa. They walked over, took Kalvin's jacket and the money, then Bangura stabbed Kalvin in the chest.
The tenant told the court that during the frenzy, the attacker had attempted to stab him too, but he managed to swerve out of the way.
When Kalvin had been stabbed, the court was told Bangura said, ‘It’s done, let’s get out of here,’ before leaving and the tenant hearing a car screeching up the road.
The tenant described walking into the lounge and hearing a change in Kalvin’s breathing and realising he had died. He then also left the address, leaving the door unlocked. He stated that he left a window open on purpose in the hope that Kalvin would be found and left Kalvin's phone near his body so he could be identified.
Another witness gave evidence to confirm Dugdale had visited the Lefroy Road flat alongside Bangura and Hall.
Bangura had told the witness that the male tenant in the flat had a £200 drugs debt they wanted to collect from him, and Hall had suggested the trip there in person. The witness also positively identified Bangura in an ID parade.
The male tenant told the court that when Kalvin arrived at his flat, he had a large knife with him, around 14 to 15 inches in length which he kept in a black sheath.
The trial heard that the tenant did various ‘runs’ for Kalvin delivering orders of the drugs and giving the money to Kalvin. He told the court he worked out Kalvin must work for the Batman line as he had called to access drugs and Kalvin’s phone rang in the flat.
On the day Kalvin’s body was discovered, a member of the public had flagged down a police patrol and told them a boy had been stabbed, and his body had been left in the flat.
Officers arrived around 11pm and found the door to the flat unlocked with Kalvin laying over the arm of the sofa on his back with a slit in his clothing. His body in a state of decomposition.
At the trial, CCTV evidence showed a white Audi A3, believed to be an unlicensed taxi, stopping on the opposite side of Lefroy Road at 1pm on 15 September where the occupants walked in the direction of the flat where the murder took place.
The vehicle is then seen again on CCTV the following day 16 September at 3.07pm on Shorncliffe Avenue where Dugdale lives. Later that day, at 3.59pm, the Audi is spotted on Rose Lane travelling from Prince of Wales Road.
CCTV captures Bangura having changed his clothing walking from Prince of Wales Road and into the train station. A clearer image of a man was seen at the train barrier and believed to be Leon Bangura.
Bangura denied threatening another person with a knife and was found not guilty at the same hearing. He had previously pleaded guilty to being concerned in the supply of heroin, being concerned in the supply of crack cocaine, possession with intent to supply crack cocaine and possession of a knife at an earlier hearing.
"We love you Kalvin"
Kalvin’s mother asked police to issue this tribute on her behalf:
“It is so devastating what has happened to my son. It has left our family in a million pieces which we will never recover from.
“Kalvin was a son, a grandson, a brother, a cousin and a friend to us all.
“We will remember and miss Kalvin all the days of our life.
“We love you Kalvin, rest in heavenly peace until we meet again.”
"Kalvin’s family have shown immense courage"
Detective Inspector David McCormack, Senior Investigating Officer, said:
"Kalvin’s family have shown immense courage throughout this lengthy and harrowing trial, listening to distressing evidence with dignity and strength.
"Our Family Liaison Officers have been a vital lifeline for them, ensuring they were supported and informed every step of the way.
"This case demanded an extraordinary level of specialist detective work and intelligence gathering. From the moment Kalvin’s body was discovered, officers worked tirelessly to trace and arrest the suspects determined to evade capture.
"Today’s verdict is a testament to that relentless commitment to securing justice for Kalvin and his loved ones."
