SAN FRANCISCO — An Antioch man who attacked the owner and two employees of a San Francisco jewelry store over a belief that they’d overcharged him was denied a new trial.

Barry White Jr., 29, argued through his appellate attorney that his convictions for murder and attempted murder should be overturned in part because of a juror misheard White’s attorney and falsely believed he had made a sexist remark. The appeals court also denied White’s contention that the trial court had withheld records about police officer witnesses that would have benefited the defense.

In 2013, White entered San Francisco’s Gift Center & JewelryMart, waited for customers to leave, and attacked the staff. He shot and stabbed Lina Lim, 51, and store owner Victor Hung, and slashed the throat of Khin Min, 35, cutting her from ear to ear. Lim and Min were killed; Hung survived.

White was apparently angry because he thought he had overpaid for a chain he’d purchased from Hung days earlier.

In 2018, after his trial the previous year, White was sentenced to life without the possibility of parole, plus another 266 years. During trial, White’s attorney argued not that White hadn’t killed the victims but that he was brain-damaged from being shot by a San Francisco officer months earlier.

White’s appeal centered on an issue that came up because of a juror who during trial wrote the judge a note about White’s attorney. It read, “Please let counsel know that asking a female colleague to, quote, ‘calm down,’ reads as sexist. This is not a question—a question for anyone, just a tip. It’s very distracting,” according to court records.

As it turned out, White’s lawyer had said “compound,” which is a shorthand way of expressing a specific legal objection to an opposing attorney’s question. White’s appeal attorney argued that the juror’s misperception was an indication that the jury was biased against the defense.

Appellate judges rejected this notion. “Given that the juror did not alert the court to any further problems, and the record offers no indication that juror (or any other juror) was biased against the defense as a result, we find no abuse of discretion in the trial court’s refusal to conduct further inquiry,” the judges wrote in the 27-page decision, handed down last month.

White’s appeal attorney also requested that the court review a sealed file containing records on six police witnesses. Before White’s trial, the trial judge granted a defense request to produce records on six officers that may tend to suggest they were dishonest. The appeals court ruled that the court hadn’t withheld any relevant records from White’s defense team.

White is currently serving his life sentence at California State Prison, Solano, according to prison records.
