Expertise in defending murder cases
I have particular expertise in defending people charge with murder. My cases have included:
R v M – shooting in East London, alleged to have been committed by drug dealers who fell out with victim. Prosecution case was that M was the driver to and from the scene of the shooting and that he knew of the common intent to shoot the deceased. Acquitted of murder.
R v A – self defence where, in the course of disarming his step father who was armed with a knife, my client stabbed him. Technical evidence on martial arts to demonstrate the manoeuvre was know to certain martial arts and explained the nature of the injury.
R v Q – mistaken ID case where 7 people ran past a person drinking outside a pub and one fatally stabbed him. Joint enterprise murder case where my client was said to be the spotter for the target. Q accepted he was the spotter but thought the intention was a fist fight, not a stabbing. Acquitted of murder and conspiracy to GBH.
R v C – Carjacking where robber fatally stabbed car owner. C was said to be the lookout and guilty by joint enterprise. Acquitted of murder.
R v M – hitman shooting where our client was said to have organised the shooting. Highly complex telephone evidence analysis. Ultimately found not guilty as the prosecution could not prove that our client had been in possession of the phone.
R v H – Woman stabbed her partner to death. Prosecution were persuaded to accept a guilty plea to manslaughter and drop the murder charge. 18 months’ imprisonment imposed and she was released shortly after the conclusion of her case.
R v S – First defendant in trial of 11, all accused of murder. A huge street fight involving knives where one youth was killed and two others seriously injured. Acquitted of murder by the trial judge after legal argument about the state of the evidence.
R v S – 15 year old was robbed. He was accused of inciting his cousins to shoot the person who had robbed him – acquitted of murder.
R v K – Man pushed leading human rights lawyer under tube train – acquitted of murder by reason of diminished responsibility.
