Which case introduced the concept of exigent circumstances in relation to escapes?

The case that introduced the concept of exigent circumstances in relation to escapes is Frye v. U.S. This case had a significant impact on the understanding of how exigent circumstances can justify warrantless searches and seizures, particularly in situations involving the immediate need to prevent the destruction of evidence or to apprehend a suspect who is in imminent danger of escape.

In Frye v. U.S., the court evaluated the validity of a warrantless entry by officers under the belief that exigent circumstances existed. The ruling established that when law enforcement officers have a reasonable belief that a suspect may flee or that evidence may be lost if they do not act quickly, they may have the authority to enter a property without a warrant. This principle is crucial in allowing law enforcement to respond effectively to urgent situations, especially those concerning escapes.

The other cases listed, while significant in their own right, do not specifically address the concept of exigent circumstances related to escapes in the same way that Frye v. U.S. does, making it the correct answer to the question.
