The best way to find out if a person is lying is to observe their body language and facial expressions. Pay close attention to how they're responding to your questions, and look for signs of discomfort or deception such as fidgeting, avoiding eye contact, or changing their story. Additionally, ask follow-up questions that require them to provide details about the information you've already obtained from them, as this can help determine if they are being truthful or not.
