It is now five years since Indiana University student Lauren Spierer disappeared after a night out with friends in Bloomington.
The Indiana University student was 20 years old when she vanished in June of 2011 after a night out with friends near campus.
Her mom, Charlene, posted a note on Facebook Friday morning, calling her daughter's disappearance five years ago "indescribable, unbelievable, unconscionable."
Charlene tweeted this week: "6/3/2016 too many years, too few answers. Pls follow and RT @NewsOnLaurenS. Don't let them forget."
Bloomington Police say Lauren's disappearance is still a top priority, and they've dedicated hundreds of hours of overtime to solve the case.
Her mother's Facebook post also quoted Nelson Mandela, saying, "It always seems impossible until it's done."
"That’s how I feel about Lauren’s case," Charlene wrote. "After five years, and no matter how many more we face, some day, we will get the call, and what has seemed impossible, will be done.
"Rebecca, Dad and I are loving you, dear sweet Lauren, every second of every day and you remain in our hearts always."
In 2011, you couldn't walk down a Bloomington street without seeing pictures and posters of Lauren Spierer. They are long gone. The investigation has faded from view, but is very much alive in people's minds.
Artist Eve Mansdorf painted a picture of campus just inside the Sample Gates. It is missing the IU student almost everyone has heard of.
"It kinda makes me nervous when I hear the name," said junior Dana Hudson.
Lauren Spierer's disappearance is an unsolved, unsettling mystery.
"A lot of people would like closure," Nichols explained. "They would like closure for the family. They would like closure for the community," said Teresa Nichols, a doctoral student and researcher.
Spierer, an outgoing 20-year-old, vanished after a night and morning of heavy partying with friends. She was alone when video security cameras captured her walking out of frame - never to be seen again.
Brittanie Dike was just 13 and remembers it like yesterday.
"Parents were not open to letting kids walk around by themselves after that," she said.
Five years later, the mere mention of Lauren Spierer is a warning to students.
"They understand they need to be more careful, especially women," senior Jade Mays said.
Even to this day.
"Yes," Mays said without hesitation.
For weeks, hundreds of volunteers helped scour the area where Spierer disappeared, as well as broad expanses in rural Monroe County.
In a news release marking the fifth anniversary of their investigation, Bloomington police said they've worked 2,500 hours of overtime, checked 3,500 tips, and investigated numerous potential suspects.
Yet there have been no arrests, or sign of the young woman's remains.
Robin Nordstrom lives in Bloomington and follows the case.
"It does make you wonder," she said.
Nordstrom is beginning to doubt if the mystery will ever be solved.
"In some things in life, there isn't an answer. Some things we have to accept," Nordstrom explained.
But, she added, it's "almost impossible" to accept.
Bloomington police insist this is not a cold case. Detectives according the news release are working it virtually every day, hoping to get a tip - a small detail that leads to something big.
