Alfonso Rodriguez Jr.

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.

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 21 by attempting to rape a woman he asked to give him a ride home.

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.

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.

Four minutes into their conversation, Lang reports Sjodin was saying "Okay, okay," before the call abruptly ended.

Lang suspected that the call was just 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.

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.

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.

Police reports indicate that Rodriguez claimed to have been near Columbia Mall on the evening of Sjodin's disappearance, reportedly watching Once Upon a Time in Mexico at the Columbia Mall Cinema 4.

This claim was disproven as the film was not screening at that cinema or any other local theater at the time.

Further investigations revealed receipts from Rodriguez's purchases at various stores around the mall, including one from a nearby Menards store for a knife.

Notably, Rodriguez possessed two specific tool kit knives available only at a certain home center store located approximately a mile from the mall.

These knives, however, were not purchased on the day Sjodin vanished, and their exact purchase date remains unknown.

In Rodriguez's car, police found one of these tool kit knives submerged in a cleaning solution in the rear wheel well.

Additionally, a woman's shoe and another knife with blood matching Sjodin's DNA were discovered in the vehicle.

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; she had been beaten, stabbed, and 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.

Because Sjodin had been taken across state lines, the crime became a federal case under the Federal Kidnapping Act.

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 state has 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 U.S. Attorneys Keith Reisenauer and Norman Anderson prosecuted the case against Rodriguez.

On August 30, 2006, Rodriguez was convicted in federal court of kidnapping resulting in death for 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 R. Erickson.

He is imprisoned at the United States Penitentiary, Coleman in Florida.

Judge Erickson arranged that Rodriguez would be executed in South Dakota.

Rodriguez later admitted his guilt in a death row interview with Dr. Michael Welner on June 28, 2013.
