Closing arguments in Carlos Trujillo's trial are expected Monday. The final defense witness took the stand Friday in Stamford Superior Court.
The 49-year-old Bridgeport man is charged with murder in the death of Andrew Kissel. Trujillo was Kissel's chauffeur.
Kissel was found dead in his basement in April 2006, just days before he was to plead guilty in a multimillion-dollar fraud case.
Trujillo's cousin, Leonard Trujillo of Worcester, Mass., pleaded guilty last year to reduced charges of manslaughter and conspiracy and testified against his cousin.
