Prosecutor: Defendant in SF jewelry store killings thought he'd been overcharged by about $300

Prosecutors say the suspect charged with the gruesome killing of two San Francisco jewelry store clerks and critical wounding of the shop owner believed he had been overcharged by about $300.

Assistant District Attorney Scot Clark told a judge during 23-year-old Barry White's first court appearance Tuesday that White returned to the store Friday to dispute a purchase from May.

Clark said White thought the item did not have as many grams of precious metal as advertised, and he had overpaid by about $300.

White is accused of shooting store owner Vic Hung and store clerk Lina Lim and of cutting clerk Khin Min from ear to ear with a knife. Min and Lim died.

White did not enter a plea. His attorney said the charges were only allegations.
