Title 18 › Part III— PRISONS AND PRISONERS › Chapter 313— OFFENDERS WITH MENTAL DISEASE OR DEFECT › § 4243
When a person is found not guilty only because they were insane at the time of the crime, the court must send them to a suitable hospital or facility until they meet the rules for release. Before the release hearing, the court orders a psychiatric or psychological exam and report. A hearing must happen within 40 days of the verdict. If the crime involved bodily harm or serious property damage (or a big risk of those), the person must prove by clear and convincing evidence that letting them go would not create a substantial risk of harm. For other crimes, they must prove that by a preponderance of the evidence (more likely than not). If the court is not convinced under those standards, the person goes into the custody of the Attorney General. The Attorney General should try to turn the person over to the state where they live or were tried if that state will take responsibility. If no state will, the Attorney General must hospitalize the person until a state accepts them or until their condition improves enough that release or conditional release under a treatment plan would not create a substantial risk of harm. If the hospital director says the person has recovered, the director files a certificate with the court and the court either orders discharge or holds a hearing. If the court finds the person is safe, it will either release them or allow conditional release with a prescribed treatment plan and a requirement to follow it. If the person breaks the plan or there is probable cause they did, they can be arrested and the court will decide if they must be sent back to a facility. For certain people from the District of Columbia whom the United States still pays for, the Attorney General can ask a federal court to transfer custody to the federal government after giving notice and up to 15 days to respond; transferred persons get the same review and rules.
