John Arthur MacLean, 78, was found guilty Friday in a trial that focused on an attack of a 15-year-old inside a Boca Raton residence in 1976. Cold case detectives arrested MacLean in 2012 based on DNA evidence.

The defendant previously stood trial in 2018 and was found guilty as charged, but an appellate court later ordered a new trial. The victim again bravely testified last week.

Assistant State Attorneys Alexa Ruggiero and Nicole Corring of our Special Victims Unit prosecuted the case.

The court ordered MacLean’s life sentence to run concurrent to another life sentence that he has been serving – for an armed sexual battery in 1977.
