LOS ANGELES -- A judge declared a mistrial Thursday on dozens of remaining counts against five former elected officials accused of misappropriating public funds in a working-class California city.

The move came after jurors who had convicted the officials of 21 criminal counts the day before said they could not reach a verdict on the other allegations.

Superior Court Judge Kathleen Kennedy declared the mistrial after a day of fruitless deliberations by the panel.

Jurors reached mixed verdicts on Wednesday, convicting the former mayor and four former Bell City Council members of 21 counts of misappropriating public funds and acquitting them of 21 other counts.

The case involving the modest 2½-square-mile Los Angeles suburb has become a national symbol of political greed. Authorities allege a salary-inflating scheme that drove the city to the brink of bankruptcy was masterminded by former City Manager Robert Rizzo, who is expected to go on trial with his former assistant on similar charges later this year.
