Understanding Oklahoma’s Mary Rippy Violent Crime Registration Act

Most Oklahomans are familiar with the state’s sex offender registry, but fewer are aware of a similar requirement for violent crimes. The Mary Rippy Violent Crime Offenders Registration Act (57 O.S. § 591 – 599.1) mandates that individuals convicted of certain violent offenses register with local law enforcement.

At Kania Law Office, our criminal defense team represents clients across Tulsa, Tahlequah, Wagoner, Claremore, Okmulgee, and Creek County. We know that navigating post-conviction requirements can be confusing and fraught with legal risks. Here is what you need to know about the Mary Rippy Act and what constitutes a violation in Oklahoma.

What is the Mary Rippy Violent Crime Registration Act?

Enacted in 2004 following the tragic murder of 89-year-old Mary Rippy, the law requires individuals who have been convicted of—or received a deferred or suspended sentence for—specific violent crimes to register their address with local authorities. Much like the sex offender registry, the state’s violent offender registry is fully searchable by the public.

Not every assault or violent act triggers this requirement. The statute specifically lists the crimes that mandate registration:

• First-degree murder
• Second-degree murder
• First-degree manslaughter
• Shooting with intent to kill, drive-by shootings, and assault and battery with a deadly weapon
• Assault with intent to kill
• Bombing
• Certain crimes involving severe abuse
• Any substantially similar crime committed in another state or jurisdiction

Anyone required to register in Oklahoma must typically do so for a period of 10 years following the completion of their sentence. Crucially, the law also applies to individuals moving to Oklahoma who have a prior conviction from another state for an equivalent offense.

What Constitutes a Violation?

A violation of the Mary Rippy Act occurs when an individual fails to properly register as an offender. Under Oklahoma law, securing a conviction for failure to register requires the State to prove beyond a reasonable doubt that:

1. The person was convicted of (or received a suspended/probationary/deferred sentence for) one of the qualifying violent crimes.
2. The person received actual notice that they were required to register with the Department of Corrections and the local law enforcement agency in the area where they reside or intend to reside.
3. The person subsequently failed to register.

The Importance of “Notice”

The element of “notice” is a critical defense point in these cases. The Oklahoma Court of Criminal Appeals has explicitly ruled that a defendant cannot be convicted of failing to register if they were never officially notified of their duty to do so. The state must prove that you were made aware of this requirement before they can charge you with violating it.

Penalties for Violating the Act

Failing to register under the Mary Rippy Act is not treated as a minor clerical oversight—it is charged as a separate felony offense. A conviction for failure to register is punishable by up to five years in prison and a maximum fine of $5,000.
