Dru Sjodin: Abduction, Overturned Death Sentence, and Dru’s Law

The Dru Sjodin case is the 2003 abduction and murder of 22-year-old University of North Dakota student Dru Katrina Sjodin by Alfonso Rodriguez Jr., a recently released Level III sex offender, and the federal prosecution and legislation that followed. Rodriguez was convicted of kidnapping resulting in death and sentenced to die, but that sentence was later vacated and replaced with life without parole. The case is the reason the national sex offender public registry carries Sjodin’s name.

Who Dru Sjodin Was

Dru Katrina Sjodin was born on September 26, 1981, in Minneapolis and grew up in Pequot Lakes, Minnesota, where she was voted Homecoming Queen her senior year at Pequot Lakes High School.¹²³

She was an artist working in painting, drawing, photography, and pottery, played basketball, volleyball, and golf, and belonged to the Gamma Phi Beta sorority, through which she worked with underprivileged teens.² She held two jobs alongside a full course load and had a trip to Australia planned for the spring of 2004.¹

The Abduction From Columbia Mall

On the afternoon of November 22, 2003, Sjodin left her job at the Columbia Mall in Grand Forks. That night she was scheduled to chaperone a dance for underprivileged teens between her two jobs.² When she failed to appear for her second shift, police went to the mall and found her car still in the parking lot with a knife sheath lying beside it.⁴

Investigators traced her cell phone signal to a tower near Crookston, Minnesota, roughly 25 miles east of Grand Forks across the state line. Three days later, on November 25, one of Sjodin’s shoes was found under a bypass near Crookston.⁴ Because the crime appeared to cross state lines, the FBI and dozens of other agencies joined an investigation that eventually involved more than 200 officers — the largest in the history of the Grand Forks Police Department.⁵

How Investigators Identified Alfonso Rodriguez Jr.

Investigators began interviewing people in the Grand Forks area with prior kidnapping or sex offense convictions. That led them to Alfonso Rodriguez Jr., a Level III sex offender living in Crookston. Rodriguez had been released from a Minnesota prison in May 2003, six months before the abduction, after serving a full 23-year sentence for an attempted abduction in Crookston in 1979.⁶ He also had two prior convictions for aggravated rape dating to 1974.⁷

His alibi fell apart quickly. Rodriguez told investigators he had been watching a movie at a Grand Forks mall the day Sjodin disappeared, but police confirmed the film was not playing that day.⁴ A search of his car turned up small blood splatters in the back seat that matched Sjodin’s DNA, along with a knife in the trunk that matched the sheath found at the mall.³ He was arrested on December 1, 2003, nine days after Sjodin disappeared.⁸

Discovery of Sjodin’s Body

Despite volunteer searches that continued for months, Sjodin’s body was not found until April 17, 2004, in a drainage ditch outside Crookston, uncovered by freshly melted snow. Her phone was recovered nearby. She was naked below the waist, her hands were tied behind her back, and rope and plastic bag remnants were around her neck.⁴

Hair and fiber samples recovered from Sjodin’s body matched Rodriguez and his possessions. Forensic testing indicated the presence of semen, and the most likely causes of death were identified as asphyxiation or suffocation, a slash wound to the neck, or exposure to the elements.⁴

The Federal Trial and Death Sentence

Because the kidnapping crossed the North Dakota-Minnesota border, the case fell under federal jurisdiction. Rodriguez was charged under 18 U.S.C. § 1201(a)(1) with kidnapping resulting in death.⁴ Neither North Dakota nor Minnesota had the death penalty, but the federal kidnapping statute did.⁹

Drew Wrigley, then U.S. Attorney for North Dakota, led what he later described as the longest federal criminal trial in the state’s history.¹⁰³⁴⁵

Why the Death Sentence Was Overturned

The Eighth Circuit affirmed Rodriguez’s conviction and death sentence on September 22, 2009, though it noted certain prosecutorial comments during the penalty phase were improper.¹¹ Rodriguez then pursued a federal habeas corpus petition. On September 3, 2021, Judge Erickson — the same judge who had originally imposed the death sentence, now sitting on the Eighth Circuit — issued a 232-page ruling vacating the death sentence and ordering a new penalty phase trial.¹²

Erickson found two constitutional deficiencies. First, the trial testimony of Ramsey County Medical Examiner Michael McGee was “unreliable, misleading and inaccurate.” McGee had testified that semen was deposited within 24 to 36 hours of Sjodin’s death, but those conclusions were not supported by his own autopsy reports or by scientific literature, and Erickson concluded McGee had been “guessing” on the stand. Second, the judge ruled that Rodriguez’s defense attorneys provided ineffective assistance by failing to adequately explore a potential insanity defense and by limiting a mental health evaluation that could have uncovered evidence of severe post-traumatic stress disorder.¹²

Erickson emphasized that the conviction itself remained intact. “While it is beyond question that Rodriguez abducted and murdered Sjodin,” he wrote, “the evidence now in the record has led the Court to conclude that errors were made that violate the United States Constitution such that due process demands a new penalty phase trial be held.”¹²

From Death Row to Life Without Parole

Federal prosecutors filed a notice to appeal Erickson’s ruling in March 2022 but voluntarily dismissed the appeal weeks later, with both sides agreeing to proceed to resentencing. At that time, prosecutors said they still intended to seek death.¹³¹⁴

On March 14, 2023, the U.S. Attorney for the District of North Dakota, acting at the direction of Attorney General Merrick Garland, formally withdrew the government’s notice of intent to seek the death penalty. The withdrawal came during Garland’s broader moratorium on federal executions while the federal execution process was being reexamined.¹⁵ In May 2023, Judge Erickson formally amended Rodriguez’s sentence to life in prison without the possibility of parole.¹⁶

Drew Wrigley, by then North Dakota’s Attorney General, criticized the decision publicly, noting that a federal jury had unanimously sentenced Rodriguez to death in 2006 and that the conviction and sentence had been upheld by the Eighth Circuit and reviewed by the Supreme Court. He added that Rodriguez would nonetheless remain imprisoned for life.¹⁰ Rodriguez was moved from federal death row at the U.S. Penitentiary in Terre Haute, Indiana, to the Coleman II high-security penitentiary in Sumterville, Florida.¹⁷

The Minnesota Settlement Over Rodriguez’s Release

A central question after the case was why Rodriguez, with two rape convictions and an attempted abduction conviction, had been released from prison without being referred for civil commitment. Sjodin’s parents, Allan Sjodin and Linda Walker, pursued a claim against the Minnesota Department of Corrections, arguing that a department psychologist had improperly decided against recommending Rodriguez for civil commitment on his release.¹⁸

In July 2007, the family reached a $300,000 settlement with the state.¹⁹ The state admitted no wrongdoing, liability, or violation of law.¹⁸ Linda Walker said the family’s real objective was accountability rather than money: “We never talked about the money. What we really wanted was something in writing from the state, ‘I’m sorry. We were wrong.'”²⁰

The case reshaped Minnesota’s handling of sex offenders nearing release. In December 2003, weeks after the abduction, the Department of Corrections made 236 additional referrals for civil commitment after an extensive review. Commitments to the Minnesota Sex Offender Program peaked at 88 in 2007, nearly six times the 2003 level, and from 2004 through 2008 judges committed 321 sex offenders, compared with 56 from 1999 through 2003.²¹ The state also passed tougher sentencing laws for sex offenders and increased funding for electronic monitoring and supervision.¹⁸

Dru’s Law and the National Sex Offender Public Website

The case became a catalyst for federal legislation. Senator Byron Dorgan of North Dakota introduced “Dru’s Law,” aiming to create a publicly searchable national sex offender database. The Senate passed Dru’s Law twice as standalone legislation before its provisions were incorporated into the broader Adam Walsh Child Protection and Safety Act of 2006.²² Representative Earl Pomeroy, also of North Dakota, authored the House version.²³

The Adam Walsh Act passed the Senate by unanimous consent on July 20, 2006, and was signed into law by President George W. Bush on July 27, 2006.¹ The Act renamed the existing National Sex Offender Public Registry as the Dru Sjodin National Sex Offender Public Website (NSOPW.gov), creating a single portal for the public to search sex offender registries across all 50 states, U.S. territories, and federally recognized tribal jurisdictions. It also established the SMART Office within the Department of Justice to administer federal registration standards and coordinate training and technical assistance.²⁴

Before the Act, national sex offender database access had been restricted to law enforcement. Dorgan described the legislation as closing “holes in the law” by making tracking information accessible to ordinary citizens across state lines.²³

Family Advocacy and the Sjodin Scholarship

Allan Sjodin and Linda Walker became public advocates for stronger sex offender laws, testifying at the Minnesota State Capitol and appearing at national events, including an abuse conference in Baltimore. Allan Sjodin said their objective was to “force the state and federal governments to act against these criminals, to pass the appropriate legislation, properly fund it and make the legislation work.”¹⁹

The University of North Dakota established the Dru Sjodin Memorial Scholarship, which funds tuition and fees for one full academic year for a female student entering her sophomore, junior, or senior year, with preference for students from North Dakota or Minnesota who demonstrate financial need. Recipients collaborate with the Community Violence Intervention Center at UND and take part in awareness events such as the Clothesline Project and the Take Back the Night Rally, causes Sjodin herself supported during her time at the university.²⁵
