Which of the items was not found at the murder scene?

Question

Quizplus · Accepted Answer

The murder weapon is often a key piece of evidence in solving a case, but it is not always found at the scene of the crime. In this context, while bloody shoeprints, a bloody glove, a knitted watch cap, and a pair of eyeglasses might be left behind by the perpetrator or victims, the absence of the murder weapon suggests it was removed by the perpetrator to avoid leaving direct evidence linking them to the crime.
