France has just requested the extradition of an American, accused of a double assassination preceded by a trip of 8,000 km between Colorado, where he lives, and Saint-Maur-des-Fossés, where the mother of his children, killed with the man she had just met.

The affair had started as an enigma at the end of July: a man and a woman found naked, entwined in a bed, shot dead in Saint-Maur-des-Fossés in Val-de-Marne.

Two executives, two quads without history, who had recently met, he, single, she separated from her American husband, a senior computer executive, who lives in Colorado, 8,000 km from the crime scene.

And yet, it is he who would have committed this double murder.

A weapon sent from the United States by post

His alibi did not last long in the face of the Criminal Squad's investigations.

The ex-husband planned everything from the United States.

Using the pretext of a professional meeting in Paris, he made a transatlantic return trip just to come and kill the mother of his children.

With a gun in his luggage?

No, too risky.

In his premeditation, he bought a pistol in America, which he had shipped to France, in poste restante, in Paris, where he quietly recovered the package.

He then went to his ex, in Saint-Maur-des-Fossés, of which he had kept the keys to the apartment, and it is there that he would have surprised his former companion with his new lover, a collateral victim in this double murder.

The suspect was therefore arrested in the United States and allegedly confessed to American investigators.

The French authorities have requested his extradition.
