Spurs center Tim Duncan spent all his free time this week studying law books and building a case in an attempt to exonerate a death row inmate wrongfully incarcerated at Ohio's Mansfield Correctional Institution. 'For more than 10 years, Randolph Morgan has been imprisoned for a crime he did not commit, mainly because of the testimony of an unreliable witness, one Cheryl McInerney,' said Duncan, who has devoted the past three offseasons to earning a law degree at San Antonio State and in August passed the bar exam in both Texas and Ohio. 'I have met with medical examiners and several forensic pathologists, and they concur that the available DNA evidence is more than sufficient to prove the innocence of my client.' Duncan went on to score 14 points against the Los Angeles Clippers Monday night before flying to Ohio to persuade the governor to issue a stay of execution for Morgan.
