BLOOMINGTON, Ind. (WISH) - Monday marks two years since IU student Lauren Spierer was last seen in Bloomington.
Her parents aren't giving up their fight for information, remaining active on Twitter and Facebook, with help from friends and even complete strangers.
Charlene Spierer said via phone Sunday, it was a difficult day. She said they hope to get to Bloomington in July.
Spierer disappeared the morning of June 3, 2011, after a night out with friends. Police say she went to Kilroy's in Bloomington, then to friends' apartments. She was last seen walking in the direction of her home around 4:30 a.m.

The men who were last believed with her, were thrust into the spotlight.
One of those boys told police Spierer and others that night crushed up and snorted Klonopin, a drug used for seizures and panic attacks and they may have taken cocaine. He claims Spierer fell twice on her head.
The Spierers say the family of Laurens boyfriend "defamed" her by bringing accusations of drug abuse just days before the two year anniversary.
Nadine Wolff, his mother, told the Journal News "If Jesse was guilty of anything, he was guilty of taking care of Lauren who had serious drug issues".
Wolff says he would threaten to call her parents and Lauren would say, "if you do I'll break up with you."
Now the mother of her boyfriend at the time tells "The Journal News" quote "That poor little girl is not with us today because of her drug abuse".
In a written statement they say, "We are appalled that the Wolffs have defamed our daughter knowing that Lauren will never have the opportunity to respond."
They call it "shameful and hurtful".
The Spierers spoke with The Journal News, in New York state, to explain they're hoping those young men would take lie detector tests, administered by police.
"I just don't understand as a parent, how these boys and their families have allowed this to go as far without doing everything they could possibly do. They maintain that they have, I don't see it," Robert Spierer told The Journal News.
"Living two years without Lauren has been a nightmare," they added.
In just the last couple months, billboards with Lauren's name and image on them have been rejuvenated in Bloomington.
The Spierers continue to speak up, saying they believe someone knows something.
24-Hour News 8 tried to contact the young men who last saw Spierer, but no one returned our phone calls.
Bloomington Police released a statement saying they've received more than 3,000 tips, since Lauren's disappearance. 166 of those were received in 2013.
They say the investigation is still active.
