A woman from Texas has pleaded guilty to her role in Vanessa Guillen’s killing.

The only suspect arrested in connection with Vanessa Guillén’s death at a Texas military base in 2020 pleaded guilty Tuesday to charges including assisting in the disposal of the soldier’s body near Fort Hood.

According to the US Attorney’s Office, Cecily Aguilar, 24, pleaded guilty in federal court in Waco, Texas, to one count of accessory to murder after the fact and three counts of making a false statement. Although no date for sentence has been set, Aguilar faces up to 30 years in prison and a $1 million fine.

Authorities say Aguilar assisted her boyfriend, Army Spc. Aaron Robinson, 20, of Calumet City, Illinois, in killing, dismembering, and disposing of Guillén’s body in the woods. Robinson committed suicide on July 1, 2020, the day Guillén’s remains were discovered.

“Cecily Aguilar’s guilty plea today was another step on the long path toward justice for Vanessa, my client, and her courageous family,” Guillén family attorney Natalie Khawam said in a statement.

Aguilar’s defense attorney, Lewis Berray Gainor, did not immediately reply to a request for comment.

Guillen’s death, as well as her family’s claims that she was harassed and abused at the Texas post, spurred a social media movement of former and present service members who used the hashtag #IAmVaessaGuillen to share their own stories. In honor of Guillen, state and federal politicians passed laws in 2021 that stripped commanders of some authority and provided survivors more alternatives for reporting.

Guillén was reported missing in April of 2020. Aguilar allegedly assisted Robinson in disposing of Guillén’s body after he bludgeoned her to death. Guillén’s family has stated that they feel Robinson sexually harassed her.

According to investigators, Aguilar, a civilian, later assisted Robinson in mutilating and concealing her remains.

Aguilar first pleaded not guilty to three conspiracy charges two weeks after Guillen’s bones were discovered. Authorities say Aguilar admitted to her role, and a judge denied her defense team’s request to have the confession thrown out because investigators did not read her Miranda rights beforehand.
