This motorcycle, which allowed the suspect to escape and cross the border, was located in the Spanish border region of Aragon, a source told AFP.
An important search system had been in place since Tuesday morning around Jaca, a small Spanish town located about 200 km from the scene of the crime, to get hold of this man, whose identity has not been confirmed by French and Spanish authorities.
According to a source close to the investigation in France, a love rivalry is at the origin of this double murder.
Physical education and French teachers
The suspect is said to be the teacher's companion and the father of her two children.
The family lived in the small town of Barbazan-Dessus and the couple was in the process of separating.
The 32-year-old woman was found late Monday afternoon lying in a street in Pouyastruc by neighbors who alerted the gendarmes.

The two victims, Gabriel Fourmigué and Aurélie Pardon, were physical education and French teachers respectively.
He, originally from the Gers, was known for his sporting exploits.
He had won the world junior bobsleigh championship, before representing France at the Winter Olympics in Albertville in 1992 and those in Lillehammer, Norway, in 1994. The investigation was entrusted on the French side to the brigade research center in Tarbes and the research section in Toulouse.
