JACKSONVILLE (CBSMiami/AP) — A juror has been dismissed in the trial of a man accused of killing a teenager during an argument over loud music outside a convenience store.

Saturday’s dismissal comes after an online column by Jacksonville alternative Folio Weekly that quoted a former prospective juror who was dismissed because he had previously written for publication. He said the juror who was picked had questioned State Attorney Angela Corey’s competence during jury selection.

The potential juror told Folio that one of the jurors who was chosen had ridiculed Corey in private conversations.

One of four alternates will replace the dismissed juror.

The fiancee of the accused testified that the couple didn’t know the teen was dead until the next day.

Rhonda Rouer on Saturday reiterated testimony she gave in Michael Dunn’s first trial: that she was inside the store when she heard gunfire. When she came out, she said, Dunn urged her to get into the car, and they sped back to their Jacksonville hotel. She said they learned from TV news the following day that 17-year-old Jordan Davis was dead.

Michael Dunn is on trial for first-degree murder in the fatal shooting of 17-year-old Jordan Davis. Dunn was convicted of attempted second-degree murder in February but that jury deadlocked on the first-degree murder count.
