A prosecutor suggested Friday that an 89-year-old man who was thrown out of his 17th-floor window by a neighbor may have been murdered because he was Jewish, following many tragic anti-Semitic murders in France in recent years.

The victim’s body was found at the foot of his building in Lyon, southeast France, on May 17 and the 51-year-old neighbor was arrested. But investigators did not initially charge him with a racist crime.

Last Sunday, the BNVCA anti-Semitism watchdog group said it would seek to be a plaintiff in the case, citing its similarity with the 2017 murder of Sarah Halimi, a 65-year-old thrown from her window in a case that sparked national outcry.

“After social media postings were provided to us, the prosector’s office has asked judges to consider the aggravating circumstance of an act committed because of the victim’s ethnicity, nationality, race or religion,” Lyon prosecutor Nicolas Jacquet told AFP.

He did not provide examples of the posts, but Gilles-William Goldnadel, a lawyer and commentator for CNews television, said Wednesday on Twitter that the suspect had called out Goldnabel in messages, including one that told him to “remember your origins.”

“It’s no longer a question of telling us it’s the act of a mentally disturbed person. The truth of anti-Semitism must no longer be hidden,” Goldnadel wrote.

France has grappled with a sharp rise in violence targeting its roughly 500,000 Jews, the largest community in Europe, in addition to jihadist attacks in recent years.

The murder of Halimi drew particular outrage after the killer, who had shouted “Allahu akbar” (“God is greatest” in Arabic), avoided trial because a judge determined he was under the influence of drugs and not criminally responsible.

That prompted President Emmanuel Macron to seek a law change to ensure people face responsibility for violent crimes while under the influence of drugs, which was adopted in December 2021.

Mireille Knoll, 85, was savagely stabbed in her Paris residence in 2018 by two men who were allegedly seeking for “hidden treasures.”
