A Frenchman went on trial Monday for beating his wife to death and burning her body in the woods, a crime he admitted to after initially reporting her missing.

Jonathann Daval, 36, risks life in prison for the murder of his wife Alexia, whose charred remains were found hidden under branches near their town of Gray-la-Ville in eastern France in October 2017.

Daval initially said Alexia, a 29-year-old bank employee, had gone jogging and never came back.

After her death he cut a distraught figure, appearing in tears at a press conference with his in-laws and leading one of several events organised countrywide in her memory.

Three months later, prosecutors said the IT worker confessed to the murder -- beating his wife in a heated argument, knocking her face against a concrete wall, and strangling her.

He initially denied setting fire to her body, but finally admitted to that too, in June last year.

Daval changed his story several times, at one point withdrawing his confession, blaming his brother-in-law, and finally admitting to everything all over again.

On Monday, when asked by the judge whether he admitted to "being the only person implicated in the death" of his wife, Daval replied "yes", appearing close to tears.

Alexia Daval's parents, Isabelle and Jean-Pierre Fouillot, attended the hearing.

"We are here for new revelations and to highlight the horrors that Alexia was subjected to," Isabelle Fouillot said.

The crime deeply shocked France, and nearly 10,000 people turned out in the couple's peaceful town for a silent march in her memory.

The murder highlighted the scourge of violence against women at the height of the global #MeToo campaign against sexual abuse and harassment of women.

On Monday, French authorities said 125,840 women were victims of domestic violence in 2019. Another 146 were murdered by their partner or ex-partner -- 25 more than the previous year.

The Fouillots' lawyer, Gilles-Jean Portejoie, told BFMTV his clients hoped for "a fair sentence... which will take account of their pain but also the repeated lies of Jonathann Daval over the last three years."

They were also hoping he would shed light on remaining questions, including whether the murder was premeditated, he said.

"Jonathann Daval must explain what happened that evening, how they got to that point, what drove him to hitting his wife a dozen times or more, what drove him to strangling her for four or five minutes," Portejoie said.

Daval had told investigators his wife had abused him physically and humiliated him. He claimed to have lashed out in a fit of rage without meaning to kill her.

Defence lawyer Randall Schwerdorffer said the trial needed "to understand what really happened", and promised "a moment of truth".
