Police investigating a double murder in France have been left scratching their heads since the two suspects are equivalent twins.
A pair of 33-year-old brothers, named only as Samuel and Jérémy Y, are a part of five other defendants on trial for the murder of two men in 2020.
On September 14, 2020, victims Tidiane, 17, and Sofiane, 25, were shot and killed in a cellar in Saint-Ouen, a northern suburb of Paris.
Each of the dual brothers are accused of plotting the killings, but DNA found on one among the weapons can only be from one twin.
But forensic experts said they’re unable to inform which of the brothers used the gun.
One investigator said, ‘Only their mother can tell them apart.’
An identical twins share the very same DNA, making it unattainable to discern between the siblings when trying to find forensic evidence.
Police said they consider the pair also exchanged clothes, phones and ID documents to confuse authorities.
A commander told Le Parisien: ‘They exchange clothes in addition to phone lines and identity papers. For a really very long time, they’ve used this twinship of their criminal profession.’
An authority who analysed the DNA found on the weapon said there was only the presence of one among the brothers, making the case much more complicated.
An identical twins result when cells from a single egg fertilised by a single sperm divide into two, so equivalent twins are the identical gender and share equivalent DNA.
Though the DNA shared by twins is basically the identical, it might vary by lots of of single mutations, that are hard to seek out.
The twins’ trial is ongoing, attributable to conclude in late February, but it surely’s not the primary time a murder trial has been thrown into disarray over twin DNA.
Twin brothers Kailum and Kieran Nightingale were convicted of manslaughter after killing a person while attempting to buy drugs from him.
