Frank Sinatra Jr., the son of the legendary entertainer who had a long musical career of his own, died Wednesday, said manager Andrea Kauffman.
He was 72.
Kauffman said Sinatra died at a Daytona Beach, Florida, hospital. Singer Nancy Sinatra said on her Facebook page that her brother died of cardiac arrest.
“Sleep warm, Frankie…” she wrote.
Sinatra was on his “Sinatra Sings Sinatra” tour and was scheduled to perform at the Peabody Auditorium on Wednesday. An announcement on the venue’s Facebook page said the singer had taken ill.
Sinatra followed his father’s singing career path and was a 19-year-old on tour when he was kidnapped in 1963. After three days, two of the men collected a $240,000 ransom paid by his father, while the other abductor let the son free. Days later, that kidnapper confessed to his brother, who called the FBI.
The kidnappers were nabbed within hours, the FBI said.
At trial, their defense team claimed it was a publicity stunt to help the young singer’s career, but there was no evidence to support that. The men were convicted.
