A 70-year old former juror in the John Goodman trial will spend at least four months behind bars for contempt of court. 

A judge told Dennis Demartin that he single-handedly derailed Goodman's conviction in the death of a 23 year old Wellington man.  Demartin is accused of juror misconduct by not telling lawyers during jury selection that he had an ex-wife who was arrested for DUI and for admitting in a book that he conducted a drinking experiment while the jury was deliberating the fate of the polo mogul. 

The judge sentenced Demartin to five months and 29 days in jail, but said only the first 120 days must be served in jail.  The rest of his sentence can be done on house arrest.  The defense will appeal the sentence. 

Goodman goes back on trial in March.
