Kidnapping in Hawaii: Penalties, Defenses, and Federal Charges

Kidnapping in Hawaii is a Class A felony that carries up to 20 years in prison, with no probation and no suspended sentence available. The offense is defined in Hawaii Revised Statutes §707-720, and it applies when someone intentionally restrains another person with one of several specific dangerous motives listed in the statute. The charge can drop to a Class B felony if the defendant releases the victim unharmed before trial, but the exposure is still serious. Federal prosecution can also run alongside state charges when the case crosses state or international lines.

What the Prosecution Has to Prove

A kidnapping conviction requires two elements. First, the defendant restrained another person. Second, the defendant did so with one of the specific intents the statute lists. Only one of those intents has to be proven:

Holding the person for ransom or reward.
Using the person as a shield or hostage.
Facilitating the commission of a felony or escape after one.
Inflicting bodily injury or subjecting the person to a sexual offense.
Terrorizing the victim or a third party.
Interfering with a governmental or political function.
Obtaining the person’s labor or services unlawfully, whether or not a debt is involved.

The forced-labor provision is what pulls many human trafficking cases into the kidnapping statute, since victims there are often held through coercion rather than physical confinement.

How “Restraint” Is Defined

The definition of restraint sits in a separate statute, §707-700, rather than inside the kidnapping statute itself. Restraint means restricting a person’s movement in a way that substantially interferes with their liberty. For adults, that restriction has to happen through force, threat, or deception. For minors under 18 and incompetent persons, the standard shifts: restraint occurs any time someone restricts the person’s movement without the consent of a parent, legal guardian, or institution with lawful custody.¹

That difference matters. With an adult victim, prosecutors have to show force, threat, or deception. With a child, they only have to show the defendant lacked permission from whoever held legal custody. No physical force is required.

The Sentence for a Kidnapping Conviction

Kidnapping sits at the top of Hawaii’s felony classification as a Class A felony.² A conviction carries an indeterminate prison term with a maximum of 20 years, and the court has no authority to suspend the sentence or grant probation.³ That is the point where kidnapping separates from most other Hawaii felonies. A judge cannot send someone home on supervision instead of prison.

A Class A felony conviction can also carry a fine of up to $50,000.⁴

Voluntary Release Can Drop the Charge

Hawaii law offers one meaningful path to a lower charge. If the defendant voluntarily releases the victim alive, not suffering from serious or substantial bodily injury, and in a safe place before trial, the offense drops from a Class A to a Class B felony.²⁵⁴ A Class B felony still carries up to 10 years in prison.

All three conditions have to be met. Release a victim who is injured, or leave them somewhere dangerous, and the reduction does not apply. The statute uses “serious or substantial bodily injury” as the threshold, so even moderate harm can disqualify the defense.

Firearms and Extended Terms Push Sentences Higher

Aggravating factors can take a sentence past the standard 20-year maximum. Under §706-661, a court can impose an extended term reaching an indeterminate life sentence for a Class A felony when the defendant meets criteria such as being a persistent offender or committing the offense in an especially dangerous manner.⁶

Firearm use triggers a separate mandatory minimum stacked on top of the base sentence. For a Class A felony committed with a standard firearm, the mandatory minimum can reach 10 years with no parole or probation. For a semiautomatic or automatic weapon, that mandatory minimum rises to 15 years.⁷

When the Conduct Falls Short of Kidnapping

Not every case of holding someone against their will meets the kidnapping statute. Without one of the specific qualifying intents, the charge drops to unlawful imprisonment, which Hawaii splits into two degrees based on physical danger to the victim.

First-degree unlawful imprisonment under §707-721 applies when someone knowingly restrains another person under circumstances that expose the victim to a risk of serious bodily injury. It is a Class C felony, carrying up to five years in prison and a fine of up to $10,000.⁸⁵⁴

Second-degree unlawful imprisonment under §707-722 covers knowing restraint without that added element of physical danger. It is a misdemeanor, punishable by up to one year in jail and a fine of up to $2,000.⁹¹⁰⁴

The gap between second-degree unlawful imprisonment and kidnapping is enormous: one year in jail against 20 years in prison. The whole difference turns on whether prosecutors can prove one of the specific intents in the kidnapping statute. Locking someone in a room during an argument looks very different from locking them there to collect a ransom.

Custodial Interference Is a Separate Offense

When a family member takes a child or incompetent person from someone with legal custody, the charge is usually custodial interference rather than kidnapping. These cases most often arise from divorces and custody disputes, and Hawaii treats them more severely when the child is taken out of state.

Custodial interference in the first degree under §707-726 is a Class C felony. It covers violating a protective order or custody decree and removing the child from the state, taking a child under 11 from their lawful custodian knowing there is no right to do so, and removing a child from Hawaii in the absence of any custody order with intent to deprive another person of their custodial rights.¹¹ An affirmative defense is available if the person acted on a good-faith, reasonable belief that taking the child was necessary to protect them from immediate bodily injury, but it requires promptly filing a report with the family court about the child’s whereabouts along with a custody request.

Custodial interference in the second degree under §707-727 covers intentionally taking or hiding a minor without the right to do so, or taking an incompetent person from lawful custody. When the person stays within Hawaii, this is a misdemeanor. If the child or incompetent person is taken outside the state, the charge climbs to a Class C felony.¹² A grandparent who keeps a grandchild in Honolulu past the agreed return time faces a misdemeanor. The same grandparent who flies the child to the mainland faces a felony with up to five years in prison.

Federal Charges Can Stack on Top

State charges are not the only exposure. Federal kidnapping under 18 U.S.C. §1201 applies when the crime involves interstate or foreign commerce, happens in a special federal jurisdiction such as a maritime vessel or aircraft, or targets certain government officials.¹³

Federal penalties run much higher than state ones. A conviction carries imprisonment for any term of years up to life. If the victim dies, the sentence can be life imprisonment or death. Attempted federal kidnapping carries up to 20 years, and conspiracy carries the same maximum as the completed offense.

Federal law also creates a rebuttable presumption that interstate commerce was involved if the victim is not released within 24 hours. The FBI can begin investigating before that window closes if there is other evidence pointing to interstate activity.¹³

When the victim is under 18 and the offender is an adult who is not a parent, grandparent, sibling, aunt, uncle, or legal guardian, federal law imposes a mandatory minimum of 20 years. The judge has no discretion to go below it.¹³

A separate federal statute, 18 U.S.C. §1204, covers international parental kidnapping. Removing a child under 16 from the United States, or retaining a child outside the country, with intent to obstruct another parent’s custody or visitation rights, carries up to three years in federal prison. The statute allows three affirmative defenses: acting under a valid custody order obtained through the Uniform Child Custody Jurisdiction and Enforcement Act, fleeing domestic violence, or having lawful physical custody and being unable to return the child because of circumstances beyond the defendant’s control, provided the other parent was notified within 24 hours and the child was returned as soon as possible.¹⁴

Conviction for kidnapping a minor by someone who is not the child’s parent also triggers mandatory sex offender registration under the federal Sex Offender Registration and Notification Act, even when the kidnapping had no sexual component. SORNA treats non-parental abductions of children as “specified offenses against minors,” so the registration obligation applies independently of what Hawaii law requires and persists long after any prison term ends.¹⁵
