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. When Sinatra Jr. was 19 in 1963, three men kidnapped him at gunpoint from a Lake Tahoe hotel. He was returned safely after two days when his family paid $240,000 for his release. Barry Keenan, a high school friend of Nancy Sinatra, was arrested with the other two suspects, Johnny Irwin and Joe Amsler, and convicted of conspiracy and kidnapping. Keenan masterminded the kidnapping, prosecution said. Keenan was sentenced to life plus 75 years in prison, but was declared legally insane at the time of the crime, had his sentence reduced and was paroled in 1968 after serving 4-1/2 years.
