A more thorough explanation:

Definition: Locus in quo is a Latin term that means "place in which." It refers to the specific location where an event or incident is said to have taken place.

• The police were called to the locus in quo of the crime.
• The lawyer asked the witness to describe the locus in quo of the accident.

In the first example, the term "locus in quo" is used to refer to the place where a crime was committed. In the second example, it is used to describe the location of an accident. Both examples illustrate how the term is used to specify the exact place where an event occurred.
