Anthony Bourdain did not have narcotics in his body when he died this month, a French judicial official said.

Mr. Bourdain, a New York chef, author and television correspondent whose death shook fans across the world, was found dead on June 8 in a hotel bathroom in Kaysersberg, a small village in the Alsace region of France.

Police at the time ruled his death a suicide by hanging. From an investigative standpoint, the only question left was whether he had any substances in his body.

There were none, save for the trace of a nonnarcotic medicine in a therapeutic dose, Christian de Rocquigny, the local prosecutor in charge of the investigation, said in a text message to The New York Times.
