DPS report reveals motive in brutal Fort Hood killing of Vanessa Guillen

The document was filed this year by Aguilar in a “Second Motion to Suppress” meant to exclude evidence obtained in the case.

It states that when asked why Robinson killed Guillen, Aguilar explained Guillen noticed the lock screen on Robinson’s cell phone contained a picture of Aguilar.

Aguilar, the document further states, revealed Robinson was worried about getting in trouble for violating the Army’s fraternization rules - since Aguilar was still married to another soldier - and he hit Guillen in the head with a hammer.

“Robinson would go into moods in which he would not be his normal self,” Aguilar allegedly told investigators.

According to those interviewed by authorities, Robinson was having an affair with Aguilar, and the woman’s husband reportedly suspected the affair, but “Army Criminal Investigations Division would not do anything about it.”
