How would you respond to the accused suspects denial of having the blood type you identified since he has proof that he had just received a blood transfusion with type o blood?

I would acknowledge the suspect's claim regarding the blood transfusion and explain that while transfusions can temporarily alter a person's blood type, they do not change their inherent genetic blood type. Additionally, forensic testing can determine the blood type prior to the transfusion, providing evidence that supports the initial findings. It’s crucial to consider all available evidence, including the transfusion history and the forensic analysis.
