Any girl can play innocent, but her demons are what drove me wild. Her secrets, her pain she mask by laughter, her darkness she trys so hard to hide, thats what made me fall for her."

Cecily Aguilar's Role in Guillen's Disappearance

Aguilar was arrested by the police around 4 am on July 1, even though her name was concealed from the public. According to Bell County Jail, Aguilar is charged with a third-degree felony.

CBS News reported that the police complaint stated that Aguilar revealed that Robinson told her about killing a female soldier by repeatedly hitting her in the head with a hammer and putting her remains in a box.

She added that Robinson picked her up at a gas station and took her to the site and showed her the remains. Aguilar later identified the remains as Guillen's. She added that they dismembered Guillen's body using a "machete-type knife" and tried to burn it, and eventually placed her remains in three separate holes, according to the complaint.

Aguilar "did unlawfully and willfully combine, conspire, confederate and agree together and with others to corruptly alter, destroy, mutilate, and conceal an object, or attempt to do so, with the intent to impair its integrity and availability for use in an official proceeding," the complaint stated.
