The 20-year-old Guillen has been missing since April and was last seen on April 22 in the parking lot of their barracks in Fort Hood, according to the U.S. Army Criminal Investigation Command (CID). Her remains were found on June 30th.
“It was just a sad morning and a sad weekend for us,”
The main suspect of the disappearance was identified as Spc by officials on Thursday. Aaron David Robinson, who shot himself on Wednesday after being confronted by investigators, said the Killeen Police Department.
Khawam said the family had told her that Guillen had planned to file a harassment complaint against Robinson the day after her death, and that they believed Robinson got angry when she told him about it. However, Robinson informed the authorities that Guillen wanted to report that he had a relationship with a married woman, which the Guillen family denies.
Fort Hood officials said they had no knowledge of reports of sexual harassment with Robinson, but the investigation was ongoing.
Khawam said the investigators had told the family that Robinson had called a woman he had worked with to help him dispose of Guillen’s body after he took her out of the base.
A woman identified as Cecily Anne Aguilar who is the estranged wife of a former Fort Hood soldier. Aguilar was arrested by Texas Rangers in connection with Guillens’ disappearance and is in Bell County prison waiting for civil authorities to file charges, CID said.
