Inside the jury room at the second New York sex crime trial of Harvey Weinstein, things were getting tense.

The 12 jurors had already acquitted the former Hollywood mogul on one felony sex crime charge, and they had begun to deliberate on a second when the discussions suddenly turned pointed, and personal.

One juror, who had been calm and had even prayed with the others, abruptly began accusing another of having been “bought out” by Mr. Weinstein or his lawyers.

The moment, which occurred on the second day of deliberations in a case that was brought by the Manhattan district attorney’s office after its earlier sex crime conviction against Mr. Weinstein was overturned, foreshadowed the rancor and dysfunction that would ultimately consume the panel, leading it to deadlock on Thursday over the question of whether Mr. Weinstein raped an aspiring actress in a hotel room in 2013.

This account of what occurred in the jury room is based on interviews with several jurors, particularly one panelist who came forward twice to voice concerns to the judge about the behavior of his fellow jurors.

That panelist, juror No. 7, described the interactions as having grown increasingly contentious and marked by personal attacks.
