The body of a Swiss woman in her fifties, shot dead, was found Thursday evening in one of the buildings on her estate near the village of Aurignac, in the south of Haute-Garonne.
His death would go back "at the beginning of the week", according to La Dépêche du Midi.
She had lived in the region for several years.
She rented guest rooms there and bred horses at the Domaine de Lagnet.
The website for this holiday resort at the foot of the Pyrenees indicates that a Swiss couple own the property.
Was it her (former) companion who shot her?
Is it or not a feminicide?
According to a source close to the investigation, a suspect was arrested in Switzerland near Zurich.
According to the Dépêche du Midi, the man is being heard by the Swiss justice.
An autopsy was to be performed this Friday in Toulouse.
The public prosecutor's office in the Occitan capital has opened a judicial investigation which has been entrusted to the Toulouse Research Section.
