Two suspects allegedly dismembered a missing soldier's body and attempted to burn it after she was bludgeoned to death, according to a federal criminal complaint released Thursday.
Guillen went missing from Fort Hood on April 22. Human remains were found in connection with her disappearance earlier this week.
The two suspects in the case have been identified as Spc. Aaron Robinson and his girlfriend, 22-year-old Cecily Anne Aguillar of Killen, Texas.
The Army has confirmed that Robinson died Wednesday morning of a self-inflicted gunshot wound during an interaction with police. Aguillar is currently in custody in the Bell County Jail.
According to the affidavit, on April 22, Robinson said he texted Guillen to inform her he was in the arms room at Fort Hood. The message is the last known text message Guillen received to her phone.
In the message, Robinson told Guillen to read serial numbers for equipment and afterword he gave her paperwork and the serial number for a .50 caliber machine gun that needed servicing.
Robinson said Guillen left the arms room, and he believed she would have gone to the motor pool. Witnesses at the motor pool prepared to receive paperwork from Guillen claimed she did not arrive with the paperwork.
The affidavit says witnesses later saw Robinson pulling a large "tough box" with wheels, that appeared to be filled with a heavy object.
On June 30, Aguilar told authorities that Robinson told her that he had hit a female soldier in the head with a hammer multiple times in the arms room, killing her, the affidavit says. She claimed Robinson then put Guillen in a box and moved it to a location near the Leon River.
On the evening of April 22, Robinson allegedly picked up Aguilar at a gas station she worked and took her to the site near the Leon River where he had left the box.
According to the affidavit, Robinson and Aguilar dismembered the female soldier’s body, using a hatchet or ax and a machete-type knife.
Police say the suspects also made many attempts to burn the body.
