Also growing colder every day while the desire for truth still burns is the case of 18-year-old Natalee Holloway, a recent high school graduate who vanished while on a class trip to Aruba in 2005. At her father's request, so that he could access money he'd saved for Natalee's college fund to pay for her brother's tuition, she was declared legally dead in absentia by an Alabama judge in 2012.

Joran Van Der Sloot, one of the local boys questioned by police during the investigation and then arrested multiple times in connection with the case, is currently in prison in Peru for the 2010 murder of 21-year-old Stephany Flores Ramirez. Natalee was last seen getting into a car with Van Der Sloot and two of his friends, brothers Deepak and Satish Kalpoe, before failing to show up for her flight home the next morning.

But despite the world having identified a real piece of scum of the earth in Van Der Sloot, Natalee's body was never found nor has there been any real closure for Beth and Dave Holloway, the teen's parents who've tirelessly never given up their quest for justice.

"I have my answer as to what happened to Natalee, and he's sitting in prison in Peru," Beth said on Today last year. She continued, "Justice is being served for Stephany Flores, thank God. And he is in prison in Peru. But justice has not been served for Natalee."

Van Der Sloot at one point promised to tell the Holloways what happened to their daughter in exchange for $250,000, $25,000 of which Beth wired into his account, only to get more lies from him in return. He's been indicted on extortion charges and the Peruvian government says he'll be extradited to the U.S. to face them in 2038, after he's served his 28-year sentence for killing Flores. He's altered his story multiple times over the years, at one point telling Fox News he sold Natalee into slavery for $10,000 before calling back to say he'd made that up.
