Frank Sinatra Jr. has died at the age of 72, according to The Associated Press.
Born Francis Wayne Sinatra, the singer and songwriter was the son of music legend Frank Sinatra and his first wife, Nancy Barbato Sinatra.
Famously, Sinatra was kidnapped from Lake Tahoe at the age of 19 in December 1963, and was released after his father paid the ransom of $240,000.
