WASHINGTON - Frank Sinatra Jr., son of the legendary singer and actor of the same name, died Wednesday at 72 years old in Florida, USA, announced his agent Andrea Kauffman, on social networks.
Kauffman said that Sinatra Jr. died in the Daytona Beach hospital in Florida where he was taken after suffering a heart attack.
Nancy Sinatra, sister of the singer, also published on her facebook page that "the Sinatra family mourn the untimely passing of their son, brother, father, uncle, Frank Sinatra, Jr. of cardiac arrest while on tour in Daytona, Florida."
Sinatra followed in the footsteps of his father and devoted himself to the music industry. At the early age of 19, he already started performing on his professional tours.
He was kidnapped during one of his tours back in 1963. The kidnappers managed to get a ransom of $240,000 (213,000 euro) paid by his father to release him.
Sinatra Jr. used to say about his father that "his imperfections were upsetting but he was a genuine artist, and his work will endure as long as men and women can hear and ponder and feel."
