New details have emerged surrounding the murder of Nathalie Maillet, CEO of the Spa-Francorchamps F1 circuit.

Maillet was found dead at her home in Gouvy, Belgium on Sunday. The 51-year-old was found in bed with her alleged mistress Ann Lawrence Daurviaux, 53, by Maillet’s husband, Franz Dubois, who confronted the pair.

Police reports say that Dubois pulled out a gun and killed both of the women before killing himself. The public prosecutor said in a statement,

“At 00:10, the bodies of two women and one man were discovered by the police in a house in Gouvy, all three presenting gunshot wounds. According to our information, the male individual voluntarily used his firearm to kill both women, including his wife, before killing himself.”

Both Maillet and Dubois were well known figures in motorsport. Maillet spearheaded a project that oversaw the modernisation of the Spa circuit that has been in use since 1925. Dubois was a well-known team owner and co-founder of the VW Fun Cup series.

The FIA, F1’s governing body, expressed their condolences for Maillet,

“The FIA has been saddened to learn of the tragic death of Nathalie Maillet. Nathalie was the Chief Executive Officer at Circuit of Spa-Francorchamps since 2016 during which time she oversaw major development of the iconic racetrack which hosts a number of FIA championships. On behalf of the entire motorsport community, we wish to extend our condolences to her family and friends.”

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. 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. 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.”

Investigations are still ongoing with forensics and ballistics teams examining the scene.
