In a criminal trial, a person is found guilty if the prosecution can prove beyond a reasonable doubt that the accused committed the crime they are charged with. The process of determining guilt typically involves the following steps:

1. Jury selection: If a jury tries the case, a group of individuals is selected to serve as jurors.
2. Opening statements: The prosecution and defense present their opening remarks, outlining the evidence and arguments they will present during the trial.
3. Presentation of evidence: The prosecution presents evidence, including witness testimony, physical evidence, and other evidence to prove their case. The defense may also present evidence to challenge the prosecution’s case or to offer an alternative theory of what happened.
4. Closing arguments: The prosecution and defense present their closing arguments, summarizing the evidence and arguments presented during the trial.
5. Jury instructions: The judge provides instructions to the jury on the law and the standard of proof that must be met to find the accused guilty.
6. Jury deliberation: The jury reviews the evidence and arguments presented during the trial and reaches a verdict.

If the jury finds the accused guilty, they are convicted of the crime and may face sentencing. If the jury finds the accused not guilty, they are acquitted and released from custody.

The burden of proof in a criminal trial is on the prosecution, and the accused is presumed innocent until proven guilty. Additionally, the specific procedures and requirements for determining guilt can vary depending on the jurisdiction and the case circumstances.
