Gabby Petito disappearance shines light on still-unsolved missing persons cases

Defense attorney breaks down Gabby Petito case

Defense attorney Anthony Rickman lays out the case from multiple points of view.

The high-profile search for Gabby Petito came to an end this week after the FBI confirmed her remains turned up in Wyoming – but the search is ongoing for many other Americans who remain missing.

Here are some of the most prominent cases.

Jelani Day

Day, a 25-year-old graduate student from Illinois, was last seen in Bloomington on Aug. 24. His family in Danville and a faculty member at Illinois State University reported him missing after he did not show up for class for several days.

Anyone with information about Day is asked to contact BPD Detective Paul Jones at 309-434-2548 or at Pjones@cityblm.org.

Natalee Holloway

Holloway mysteriously vanished without a trace during a 2005 high school graduation trip to the paradise island of Aruba.

Her puzzling disappearance sparked a worldwide media frenzy and a massive search of the island. Though an Alabama judge declared her legally dead in 2012, Natalee's body was never found, and to this day, it is still a mystery what happened.

But one detail that has never swayed is the central suspect involved: Joran van der Sloot.

He and Holloway met at a hotel-casino that summer night, and witnesses say they saw the pair leave a nightclub together. But what transpired next has been in question ever since.

Holloway’s father and a private investigator recently sat down with Fox Nation host Nancy Grace.

Spierer, a 20-year-old Indiana University student, vanished after partying with friends. National media shined a spotlight on the case, but official and private searches turned up nothing.

Spierer was last seen walking to her apartment at 4:15 a.m. on June 3, 2011. Immediate search efforts were made all the more urgent by a heart condition that required Spierer to take daily medication.

Fox News has reached out to the Bloomington, Indiana, police department for any updates on the investigation now more than a decade old.

Her family still operates a Facebook page, with the last status update posted Aug. 7.

Dulce Maria Alavez

Now 7 years old, Alavez has been missing for two years. According to her poster on the National Center for Missing and Exploited Children website, she was last seen on Sept. 16, 2019, at the Bridgeton City Park behind Bridgeton High School in New Jersey at approximately 4:20 p.m.
