Frank Sinatra Jr., 72, dies while on tour

Frank Sinatra Jr., who carried on his famous father’s legacy with his own music career and whose kidnapping as a young man added a bizarre chapter to his father’s legendary life, died Wednesday. He was 72.

The younger Sinatra died unexpectedly of cardiac arrest while on tour in Daytona Beach, Fla., the Sinatra family said in a statement to The Associated Press.

The statement said the family mourns the untimely passing of their son, brother, father and uncle.

Sinatra Jr. was the son of Sinatra’s first wife, Nancy Barbato Sinatra, and the younger brother of Nancy Sinatra, who had a successful musical career of her own.

The elder Sinatra died of a heart attack May 14, 1998, at 82.

Sinatra Jr. was able to provide a link to his father’s music after his death, performing his work on tours.
