How many jurors are used in serious criminal offences cases?

In serious criminal offense cases, typically 12 jurors are used in the jury trial system in many jurisdictions, including the United States. Some jurisdictions may also allow for a smaller number, such as 6 jurors, in certain types of cases. The specific number can vary depending on local laws and regulations. Additionally, some cases may not involve a jury at all if a defendant opts for a bench trial.
