The landmark trial began March 26 in the Court of Common Pleas.
It focuses on Father James J. Brennan, who has been charged with attempted rape and child endangerment for alleged abuse of a 14-year-old boy in 1996, and Msgr. William Lynn, former archdiocesan secretary for clergy.
Msgr. Lynn, who has not been accused of abusing any children himself, is charged with conspiracy and two counts of child endangerment for allegedly helping the church cover abuse complaints. He faces up to 21 years in prison if convicted and is the highest ranking U.S. church official to be charged with crimes related to clergy sexual abuse.
Both Msgr. Lynn and Father Brennan have pleaded not guilty to their charges.
No information was released in court June 20 on which of the five charges the jury had agreed on.
According to The Associated Press, the judge told jurors it could take days to rehear testimony, but it was better than having to retry the case if the jury is deadlocked.
