LOUISVILLE, Ky. (WDRB) -- In June, I.U. student Lauren Spierer will have been missing for two years.

It's a thought that haunts her mother, Charlene Spierer, who continues to fight for answers.

On Facebook, Spierer writes that the family still has a difficult time accepting that she's missing. She says they won't be able to anticipate the excitement as graduation nears.

Her 22-year-old daughter went missing in June 2011 after a night out with friends.

Charlene Spierer is pleading for information to solve the case. She writes that, "Lauren did not simply vanish into thin air."

She signs her post with the words, "Just as determined as Day One."
