A rather foolish car thief unknowingly stole the car of the chief of police. The police immediately launched an investigation, and based on witness statements, four suspects were arrested who had been seen near the car at the time of the crime.

Because the chief of police took the case very seriously, he decided to personally examine the suspects and use the new lie detector from the police station. Each suspect gave three statements during the examinations, which are listed below:

Suspect A:

1. "In high school, I was in the same class as Suspect C."
2. "Suspect B does not have a driver's license."
3. "The thief didn't know that it was the car of the chief of police."

Suspect B:

1. "Suspect C is the guilty one."
2. "Suspect A is not guilty."
3. "I have never sat behind the wheel of a car."

Suspect C:

1. "I never met Suspect A until today."
2. "Suspect B is innocent."
3. "Suspect D is the guilty one."

Suspect D:

1. "Suspect C is innocent."
2. "I didn't do it."
3. "Suspect A is the guilty one."

With so many contradicting statements, the chief of police lost track. To make matters worse, it turned out that the lie detector did not work as it should, because the machine only reported that exactly four of the twelve statements were true, but not which ones.
