Both Robinson and Guillen were at the Fort Hood military base in Killeen, Texas, USA. He worked in an adjacent building from where she worked.
Aguilar is the estranged wife of a former soldier who was once at Fort Hood. She has been in a relationship with Robinson since February 22, 2020.
Initially stationed in South Carolina and then Virginia, Guillen landed in the Fort Hood military base in early 2020. She was last seen alive at 1 p.m. on April 22, 2020 in the parking lot of the Regimental Engineer Squadron Headquarters for the 3rd Cavalry Regiment at the Fort Hood military base.
Earlier that day, Guillen had been working in the armory room. She was wearing a black shirt, light purple leggings and a pair of black Nike tennis shoes.
Representing Guillen’s family is Natalie Khawam. She recently has a four-hour meeting with officials from Army Criminal Investigation Command.
Khawam told the Army Times that Robinson attacked Guillen with a hammer on April 22, 2020. The lawyer told the publication, “This heinous act caused her blood to be splashed all over the armory room.”
Guillen was reportedly on duty in the armory room when she was attacked by Robinson. After killing her, he contacted Aguilar to help him bury the victim, according to Khawam.
“At first, they tried to set her on fire but she wouldn’t burn,” Khawam said. “Then, they dismembered this beautiful U.S. soldier’s body with a machete.”
On June 30, 2020, Robinson fled post so local police issued a Be on the Lookout (BOLO) notice for him. At around 1:00 a.m. on July 1, 2020, he was found walking in the 4700 block of East Rancier Avenue in Killeen, which is around 10 miles from Fort Hood.
When approached by the U.S. Marshals Service, Killeen Police Department and the Lone Star Fugitive Task Force, Robinson turned a gun on himself and pulled the trigger. He was pronounced dead at the scene by Justice of the Peace Garland Potvin, according to Killeen Police Department News.
When search crews discovered a shallow grave along the Leon River in Bell County, Texas, which was approximately 20 miles away from Fort Hood, they found partial human remains. The identity is still unknown but Guillen’s family believes the remains belong to her and a medical examiner in Dallas, Texas is working to identify them, according to ABC 13.
