Interesting and not sure how it all fits in this case but I just got home from jury duty and I was excused because I had previously been hit by a drunk driver and injured many years ago and got a bit of questioning about NC law.
Goes something like this in NC.
"Circumstantial evidence is used during a trial to establish guilt or innocence through reasoning. This indirect evidence is the result of combining different, but seemingly unrelated, facts that the prosecution uses to infer the defendants guilt.
Most criminals are careful not to generate any direct evidence while they are committing a crime. Because of this, courts often depend on circumstantial evidence to determine the facts of the case.
An example of circumstantial evidence is the behavior of the defendant around the time that the alleged crime took place. If the defendant was charged with embezzling or stealing a large amount of money, and then went out and bought a brand-new car, the purchase of the car could be used as circumstantial evidence to prove the defendant’s guilt.
Criminal prosecutors depend on circumstantial evidence to prove their case. Civil cases are often based expressly on circumstantial evidence, when trying to establish or deny liability.
It is a popular misconception that circumstantial evidence carries less weight or importance than direct evidence. This is only partly true. While direct evidence is generally seen as more powerful, most successful prosecutions rely greatly on circumstantial evidence. Circumstantial evidence often has an advantage over direct evidence because it is more difficult to suppress or fabricate.
There are some legal experts who would even argue that circumstantial evidence is more persuasive than direct evidence."
