Jurors who deadlocked during the murder trial of a South Carolina police officer who shot a fleeing driver were far more split than it appeared before a mistrial was declared this week, the jury foreman said Thursday.

A letter sent by a juror last week during deliberations suggested that there may have been a lone holdout separating Michael Slager, the white officer, from a guilty verdict. But Dorsey Montgomery, the jury’s foreman, said that nearly half the jurors were essentially undecided at that point about whether Slager should be convicted of killing Walter Scott, a black motorist, after a traffic stop last year.

“We had one individual who was just deadlocked that he wasn’t changing,” Montgomery said during an interview Thursday morning on the “Today” show. “But yet we had five other individuals who were undecided.”

Jurors were weighing whether to acquit Slager or convict him on a charge of murder or a lesser count of manslaughter. The trial essentially put the video footage of Scott’s death — which went viral online after it was released and shows him shot in the back while running away — up against Slager’s account that he feared for his life after a scuffle with Scott over the officer’s Taser.

In a letter Friday, an unnamed juror said, “I cannot with good conscience consider a guilty verdict.” This juror also said they respected their “fellow jurors, some of which oppose my position.”

A separate note from the foreman, also delivered Friday, said it was “just one juror that has the issues” and that the “juror needs to leave.” Speaking on the “Today” show, Montgomery said that “the media misconstrued” the lone juror’s letter, though he did not address his own note regarding that juror’s status. Montgomery declined to speak about the lone juror beyond saying “he just had his own convictions.”

Following those notes Friday, the jurors asked to resume deliberations on Monday morning, and Montgomery said in the television interview that he thought “we could’ve deliberated just a little bit more to see if we could sway that particular juror and get those who were undecided to make a decision.”

Montgomery only addressed how the jurors felt on Friday and was not asked about the jury’s breakdown on Monday, when they informed the judge they were deadlocked after more than 20 hours of deliberations.

The final tally of the jurors — and how many would have convicted, acquitted or were undecided — has not been made public. On Monday, the jurors only said in a note delivered to the judge that “despite the best efforts of all members, we are unable to come to a unanimous decision” in the case.

In addition to letting people know how close Slager may have come to a conviction or acquittal, finding out how many jurors were swayed in either direction could help shape other cases stemming from the shooting.

Slager faces potentially two more trials related to the shooting, and in both cases, he could be sentenced to life in prison if convicted. Prosecutors vowed to retry Slager in state court, and he also faces a separate trial on a federal civil rights charge.

Looking ahead to a likely return to court in the case, Slager’s attorney said he planned to review the court’s transcript and the trial effort to help determine how to make a more persuasive argument.
