A Texas police officer has been fired and charged the sexual assault of a woman who he was supposed to be helping because she was too drunk to drive.

KHOU obtained video of police explaining what happened when they responded to a 911 call outside officer Oscar Araiza’s home last October.

The victim had been drinking at several nightclubs with a friend, and an off-duty female officer. After deciding that the victim was too drunk to drive at around 1 a.m., the female officer suggest that she stay at Araiza’s apartment.

“Her friend told her that it would be OK to stay at this officer’s house — this Dallas police officer’s house — because he was a good person and wouldn’t nothing happen to her,” Sgt. Marilyn Harris recalled.

Sometime after 3 a.m., the woman woke up to find Araiza naked, and raping her, according to court documents.

“She was awakened with him on top of her,” Harris said. “And he had no clothes on, and he was on top of her having sex. She said he held her face down and that she started screaming.”

Officer Aubrey Thomas recalled things in a similar way.

“She woke up to the sex assault taking place, and she recalls that she wasn’t on the couch anymore,” Thomas noted. “She remembered being in a bedroom on a bed. She didn’t know how she got there.”

“He put her hand over her mouth to try to keep her from screaming,” the officer added. “That’s what she said. But she told me that he couldn’t make her stop.”

At some point, Harris said that the woman “believed that he got scared and that he escorted her downstairs and put her out.”

That’s when the victim called 911, and waited for officers to respond.

“She was crying,” Thomas pointed out. “She couldn’t stop crying.”

Court documents alleged that Araiza “admitted to having sexual intercourse with the complainant sex was consensual.” The document also said that “Araiza had fresh scratches to his neck and arms, and stated the injuries were a result of the complainant assaulting him.”

But Thomas said that she believed the woman’s story: “In my opinion, she got assaulted.”

Araiza was fired by the Dallas Police Department in February. He was arrested on charges of sexual assault, and raping a woman without her “consent or awareness.”
