Brother and Sister Guilty of Brutal Birmingham Murder

Brother and sister convicted of murder after brutal street stabbing over minor dispute

A brother and sister have been convicted of murdering a 21-year-old man in broad daylight after a violent knife attack in Birmingham that may have been sparked by a row over a damaged bicycle or a delay during a cannabis deal.

Isaiah Marsh, 20, and Mya Marsh, 23, both of Teviot Grove, Kings Norton, were found guilty of murder at Birmingham Crown Court on Monday, following a trial that heard shocking details of the pair’s “frankly brutal” assault on Minister Enfrence in November last year.

Jurors took less than four hours to unanimously convict the siblings, who had denied murder and manslaughter.

Mr Enfrence was stabbed more than 20 times in the Medway Grove area of Kings Norton on the morning of 5 November 2024. CCTV footage showed the pair confronting the victim, with Mya brandishing a kitchen knife and later handing it to her brother during the attack.

Prosecutors said the siblings lured Mr Enfrence to the scene under the pretence of a drug deal. When Isaiah arrived shortly after being called by his sister, he launched into a sustained assault, stabbing Mr Enfrence repeatedly in the body, arms, hands and head. Despite managing to flee the scene, the victim collapsed nearby due to the extent of his injuries. Members of the public attempted to help him, but he was pronounced dead at the scene.

The court heard that after the killing, Mya walked away with Mr Enfrence’s bicycle and went to work as if nothing had happened. Her brother fled the scene by bike before later attending hospital with injuries to his hands. The pair tried to hide evidence by stashing two knives and the clothes they wore during the murder in a wheelie bin.

During the trial, Isaiah claimed he acted in self-defence, while Mya insisted she never believed her brother would actually use the knife. However, CCTV clearly showed her handing him the weapon and joining in the attack.

Detective Inspector Dan Jarratt, who led the investigation, described the killing as “a brutal and cold-hearted attack in broad daylight,” adding: “The vicious nature of the attack is highlighted by the number of wounds that Minister suffered. The callous nature shown by the two afterwards further highlighted their nonchalant attitude after taking the life of a man.”

Mr Enfrence’s family issued a tribute following the verdicts, saying:

“Minister, you have been taken from us so abruptly and this has made an impact in our lives, leaving a hole in our hearts that cannot be filled. But we are happy to say you are now with the Lord in a better place. We will meet you again in eternity.” Both defendants have been remanded in custody and will be sentenced on Thursday.
