Under Article 4, Section 2 of the U.S. Constitution, states are required to provide for the extradition of individuals who have fled from one state to another to avoid prosecution or to escape punishment for a crime. This means that if an individual has committed a crime in one state and then fled to another state to avoid prosecution, the state where the individual has fled must surrender them to the state where the crime was committed upon request. This is known as the Extradition Clause of the Constitution.
