Alfonso Rodriguez Jr.

Rodriguez maintains that he is innocent. In October 2011, defense attorneys filed a federal habeas corpus motion claiming that Rodriguez is mentally disabled.

The trial was held in federal court because Sjodin had been taken across state lines. This meant that Rodriguez was eligible to receive the death penalty if convicted, a possibility not allowed under North Dakota or Minnesota law, as neither states have the death penalty. It was the first death penalty case in a century to take place in North Dakota. U.S. Attorney Drew Wrigley and Assistant US Attorneys Keith Reisenauer and Norman Anderson prosecuted the case against Rodriguez. On August 30, 2006, Rodriguez was convicted in federal court of the murder of Dru Sjodin, and on September 22, 2006, the jury recommended that he receive the death penalty. On February 8, 2007, Rodriguez was formally sentenced to death by U.S District Judge Ralph Erickson. He is imprisoned at United States Penitentiary, Terre Haute, Terre Haute, Indiana. Judge Erickson arranged that Rodriguez would be executed in South Dakota.

Legislation dubbed "Dru's Law", which set up the Dru Sjodin National Sex Offender Public Registry, was passed in 2006 and signed into law by President George W. Bush.

Sjodin's body was recovered on April 17, 2004, just west of Crookston, Minnesota, when deep snow drifts began to melt. Crookston is also where Rodriguez lived with his mother. Sjodin's body was found partially nude and face down in a ravine. Her hands were tied behind her back and she had been beaten, stabbed, sexually assaulted, and had several lacerations including a five-and-a-half inch cut on her neck. A rope was also tied around her neck and remnants of a shopping bag were found under the rope, suggesting that a bag had been placed on her head. The medical examiner concluded that she had either died as a result of the major neck wound, from suffocation, or from exposure to the elements. Thousands of people had helped search for Sjodin, and hundreds attended her funeral.

In 2004, a scholarship in Sjodin's name was set up at the University of North Dakota.

At 4:00 p.m. on Saturday, November 22, 2003, Sjodin, a 22-year-old college student at the University of North Dakota and Gamma Phi Beta sorority member, finished her shift at the Victoria's Secret store located in the Columbia Mall in Grand Forks, North Dakota. After shopping for and purchasing a new purse from Marshall Field's, Sjodin left the mall and began walking to her 1994 Oldsmobile Cutlass. During this time, Sjodin was speaking with her boyfriend, Chris Lang, on her cell phone. Ten minutes into their conversation, Lang reports Sjodin was saying "Okay, okay," before the call abruptly ended. Lang suspected that the call was just simply dropped and because Sjodin didn't give any sense of urgency, Lang thought nothing of it. About three hours later, Lang received another call from her cell phone, but heard only static and the sound of buttons being pressed. It was reported by authorities this second phone call originated somewhere near Fisher, Minnesota, but that has remained unsubstantiated. With this second call and Sjodin not showing up at her other job at the El Roco nightclub, there was concern for her whereabouts. A week later, on December 1, a suspect, 50-year-old registered level-3 sex offender Alfonso Rodriguez Jr. (born February 18, 1953), was arrested in connection with Sjodin's disappearance.

Rodriguez had been released from prison May 1, 2003, after serving a 23-year prison term for rape, aggravated assault and kidnapping a woman. Rodriguez had also previously pleaded guilty to rape and was convicted multiple times for rape. He had a long criminal record that included repeated sexual assaults against women. He was released as a Minnesota Level 3 sex offender which meant he was highly likely to reoffend.

Dru Katrina Sjodin (September 26, 1981 – c. November 22, 2003) was an American woman who was abducted from the Columbia Mall parking lot in Grand Forks, North Dakota, by Alfonso Rodriguez Jr., on November 22, 2003. Her disappearance and murder garnered great media coverage throughout the United States and prompted the creation of the Dru Sjodin National Sex Offender Public Registry.

Alfonso Rodriguez Jr. was the son of migrant farm workers Dolores and Alfonso Rodriguez Sr., who traveled between Crystal City, Texas, and Minnesota and then decided to settle in 1963 in Crookston, Minnesota. He admitted to using many drugs during his youth and committed his first sexual assault with a knife when he was twenty-one by attempting to rape a woman he asked to give him a ride home.
