Parkland shooter's death penalty case in disarray amid judge's error, juror threats

Jury selection in the death penalty case of confessed Parkland school shooter Nikolas Cruz has lapsed into chaos.

Jury selection in the death penalty case of confessed Parkland school shooter Nikolas Cruz lapsed into disarray after potential jurors allegedly mouthed expletives and threats to the defendant in the courtroom and the presiding judge admitted committing a legal error that nearly derailed the process.

Just days after Judge Elizabeth Scherer granted a motion by prosecutors to scrap jury selection in the high profile case and start from scratch, she reversed her order on Wednesday upon hearing a counter argument from Cruz's lawyers. The case began on April 4 in Broward County, Florida.

Scherer admitted that she made an error back on April 5, the second day of jury selection, when she asked would-be jurors if they could follow the law if picked to serve on the case and then dismissed 11 who said they could not.

David Weinstein, a former federal and state prosecutor in Florida, told ABC News on Thursday that Scherer made a mistake by asking the question. He said her inquiries in the initial phase of jury selection should have been limited to questions about whether the potential jurors had a hardship that prevented them from serving on the case, which is expected to last four to six months.
