MARSEILLE, France —

French singer Charles Aznavour died in his bath of natural causes caused by heart and breathing difficulties, an autopsy has found, as tributes continued to pour in Tuesday for the legendary crooner.

Aznavour, 94, was found dead on Monday at his home in the southeast, sparking mourning across France for one of the country’s best known entertainers who sold 180 million records during his eight-decade career.

Aznavour was discovered on Monday lunchtime “lying in his bathroom bathtub, next to his bedroom,” prosecutor Patrick Desjardins told reporters near his home in the town of Mouries.

An autopsy, carried out in the southern city of Nimes, found the death “occurred in the morning of October 1, in the wake of an acute edema caused by cardiorespiratory failure,” Desjardins said.

“Foul play can be ruled out, but the circumstances surrounding the death are not precisely known.”

The body has been returned to his family.

Aznavour, who had just returned from a concert tour in Japan, had said last week that he wanted to breathe his last on stage.

The Eiffel tower was lit up in gold Monday night in his honor, while global artists such as Sting and Lenny Kravitz also lauded the “eternal” influence of the “gentleman” of French singing. — AFP
