Jurors at the landmark clergy sex-abuse trial of two Archdiocese of Philadelphia priests ended a week of deliberations Thursday with fresh signs they may be far from a verdict.Midway through a fifth day of deliberations, the jurors asked Common Pleas Court Judge M. Teresa Sarmina if they could be excused for all of Friday and Monday morning, citing graduations and family commitments. They also requested to be off Wednesday if they have not reached verdicts against Msgr. William J. Lynn and the Rev. James J. Brennan.
