Unidentified Remains Found in Search for Fort Hood soldier, Vanessa Guillen.

The search for missing Fort Hood soilder Vanessa Guillen has taken a shocking turn. According to witnesses helping with the search, remains have been found in an area where another soilder had previously been found dead.

KWTX-TV said the discovery was found within walking distance of the site where investigators found soldier Gregory Wedel-Morales' remains on June 19.

Searchers have been looking for Guillen who was last seen in April of this year. Private First Class Vanessa Guillen, 20, was last seen at a parking lot at Fort Hood, Texas, where she was stationed, on April 22. Officials said that “her car keys, barracks room key, identification card and wallet” were found in the armory room where she was working on the day she disappeared.

The Army has been under scrutiny after Guillen's family accused them of knowing more about her disappearance than they disclosed.

"Where's my sister? They know where she is and I want them to speak up and I want answers and I want them now," Lupe Guillen, Vanessa's sister, told NBC affiliate KCEN in Temple, Texas, during a protest Friday. "My eyes are dried out because I can't even cry anymore."

There is no word yet if the two missing soldiers cases are related in any way.

Detectives with the Homicide Unit have removed the remains and sent them to the Southwestern Institute of Forensic Sciences in Dallas for further review. There is no word yet on who the remains belong to.

We're praying for Guillen's family. . . this has got to be an unimaginable time for them.
