Brother and sister jailed for 'truly sickening' murder over cannabis debt

A brother and sister have been jailed for the murder of a drug dealer in a "ferocious" knife attack.

Isaiah Marsh, 21, and his 23-year-old sibling Mya Marsh were sentenced to a minimum of 20 years in prison for killing Minister Enfrence, 21, in a row over a £200 cannabis debt. Bank worker Mya was trying to buy drugs from Mr Enfrence in Kings Norton, Birmingham, when she met him armed with a kitchen knife at about 10am on 5 November, the city's crown court heard.

Judge Simon Drew KC said that Mya was the aggressor in an initial confrontation with Mr Enfrence over the debt as he sentenced the siblings on Thursday. Mya called her brother Isaiah to the scene, who "launched a ferocious attack on Minister as he lay defenceless on his back on the floor" and had intended to kill, the judge said.

Mr Enfrence suffered at least 12 stab wounds to his body, arms, hands and head in the "unprovoked" attack. He did not die instantly and managed to escape before collapsing nearby.

Judge Drew said footage of the attack, which was caught on CCTV, was "truly sickening" to watch as Mr Enfrence died a "traumatic and painful death". Siblings unanimously convicted of murder The footage shows Mya passing a knife to her brother during the stabbing.

The judge told them: "This was an attack by two people on one. That attack was unprovoked.

Members of the public, including a child in a pushchair, passed very close by while the attack was taking place." After the killing, Mya went to work "as if nothing had happened" after taking the morning off work, citing mental health problems, the court was told. Isaiah later handed himself in to the police.

A jury unanimously convicted the siblings of murder on Monday following a three-week trial. Both had denied murder and alternative charges of manslaughter.

Rachel Brand KC, representing Mya, said the attack was "utterly out of character" for her client and that Mya had shouted "stop it" and "break it up" during her brother and Mr Enfrence's struggle.

Isaiah, meanwhile, would find it "almost impossible to reconcile what he saw on the CCTV with who he is.
