The United States Army Criminal Investigation Command has confirmed that a suspect who reportedly committed suicide in Killeen early Wednesday morning was a Fort Hood soldier, and that a civilian has been arrested in connection to the disappearance of Pfc. Vanessa Guillen.

In a news release, the CID said the civilian suspect is the estranged wife of a former Fort Hood soldier, and is currently in the Bell County Jail awaiting charges from civilian authorities. They did not release the suspect's name.

According to the CID, the suspect who took his own life was a Fort Hood soldier who fled the base Tuesday. They say that as Killeen police, U.S. Marshals, and agents with the Lone Star Fugitive Task Force approached the suspect on East Rancier around 1:30 AM today, he displayed a weapon and used it to take his own life.

Meanwhile, investigators continue to work a scene where partial human remains were discovered Tuesday. Those remains have not yet been identified. According to the CID, Armed Forces Medical Examiner Services will assist with DNA and dental identification at the Southwest Institute of Forensic Science in Dallas.

Again, officials have not confirmed the identity of the remains. In a recent interview with crime reporter Nancy Grace, Texas EquuSearch founder Tim Miller said the remains were covered in cement.

Our partners at News 10 report that Pfc. Guillen's sister, Maya, spoke at a news conference in Washington DC Wednesday morning and said she spoke with the man who committed suicide, saying he laughed in her face when she asked him about her sister.

Guillen family attorney Natalie Kwaham said during the news conference that the person who shot himself was a superior who had harassed Guillen and was with her the day she disappeared, April 22. Kwaham said the search for Guillen was accelerated after she and the Guillen's family told officials who they believed to be responsible for Vanessa's disappearance.
