The family of missing Indiana University student Lauren Spierer is waiting to find out if a skull found about 60 miles from where she disappeared is hers, which would bring closure to the family's ordeal since the 21-year-old woman went missing over a year ago.

The Spierer family posted a link Saturday on their Facebook page to a news story about the discovery of the skull, found in the White River in Indianapolis, about 60 miles north of the Indiana University campus in Bloomington, where Lauren Spierer was last seen in June 2011.

In the days ahead, a family will have answers they have been desperately seeking. Will it be ours? When will you end this nightmare for our family? We will never give up. We are just as determined as we were on June 3, 2011. You need to know that. It's our promise to you. For now we continue to wait, the Facebook post read.

The skull was discovered by a fisherman in the White River near the Raymond Street Bridge in Indianapolis, WRTV reported.

Lauren Spierer's father, Robert Spierer, told the Journal News of Westchester County, N.Y., where the Spierers live, that he is anxious to find out if the skull is his daughter's, although he hasn't been given an indication one way or the other.

We don't have any information, Spierer said. We're just waiting like everyone else.

The skull is on its way to a forensic anthropologist, the Journal News reported. The specialist will try to determine the age, race and gender of the remains, according to Marion County Deputy Coroner Alfarena Bellew. Those tests usually take six to eight weeks, the Journal News noted.

Robert Spierer said the Facebook posting shouldn't be taken as an indication that the family believes the skull is that of Lauren Spierer.

The posting is just our making a comment, he told the Journal News.

The Official Lauren Spierer Updates From Her Family Facebook page is filled with remembrances of Lauren Spierer. Before Saturday, the latest large posting was from Charlene Spierer, Lauren Spierer's mother.

Charlene Spierer wrote about the person responsible for her daughter's disappearance.

Your lack of compassion will be repaid in kind ... justice for Lauren will be served. Only then will you and your family know what a nightmare truly is, Charlene Spierer wrote.  Let today be the day someone starts the conversation, reaches out and shares what they know. Let today be the day someone thinks beyond their fears and actually considers what this never ending silence is doing to our family. Let today be the day you remember what Lauren meant to you.
