The female general manager of the Belgian F1 Spa-Francorchamps circuit has been found dead in her home after her husband burst in on her in bed with her alleged mistress and shot both of them before he turned the gun on himself.

Nathalie Maillet, 51, the boss of the Spa-Francorchamps Belgian F1 circuit, was found dead at her home in the Belgian town of Gouvy in the Walloon Region yesterday (15th August).

The Local news site L’est Republican reports that Nathalie was at home with her alleged mistress, Ann Lawrence Durviaux, 53, when her husband, Franz Dubois, allegedly confronted the pair who were in the bedroom.

Dubois then allegedly pulled out a gun and killed both the women before turning the gun on himself.

Nathalie became the general manager of the Spa-Francorchamps 2016 and oversaw the modernization of the circuit which had hosted its first Grand Prix in 1925.

Dubois was also a well-known figure in the world of motorsport both as a team owner and as the co-founder of the VW Fun Cup series.

The mayor of Gouvy, Veronique Leonard, released a statement saying: “I was warned, around 2:30 am, by the police, that a double murder, followed by a suicide, had been committed in the house.”

Melchior Wathelet, Chairman of the Board of Directors of the Circuit de Spa-Francorchamps, said: ” My thoughts are with Nathalie’s family, her parents, her relatives but also her teams.”

He added: “I know how this news will upset her staff and I wish on behalf of the entire Board of Directors to offer my sincere condolences to the entire Circuit team.”

Melchior concluded his statement: “Today we are losing a very great lady, a motorsports lover and enthusiast, a true leader who will be sorely missed. Nathalie had become the face of the circuit, she embodied this passion for racing that we all share.”

Local media reports that the investigation is ongoing with forensics teams and ballistics experts examining the scene of the crime.

The motive behind the killing is yet to be confirmed.
