An undocumented Venezuelan man living in Athens, Georgia — who is the brother of a suspect accused of killing on the University of Georgia campus —— was charged Friday night with possessing a fraudulent green card, according to officials.

Diego Ibarra, 29, was charged by a federal criminal complaint and is being held in state custody, the U.S. Attorney’s Office in the Middle District of Georgia said in a press release. Ibarra could face as many as ten years in prison if convicted.

Ibarra is the brother of Jose Ibarra, 26, of Venezuela, who is facing state charges for malice murder, felony murder, aggravated battery, aggravated assault, false imprisonment, kidnapping, hindering a 911 call and concealing the death of another in connection with the death of Laken Hope Riley, a 22-year-old Augusta University nursing student who police found dead Thursday on the University of Georgia campus.

Homeland Security Investigations learned of Diego Ibarra’s undocumented presence in the U.S. on Friday when an Athens-Clarke County Police Department officer approached him earlier in the day because he matched the description of his brother as authorities were investigating the UGA murder, according to the criminal complaint and sworn affidavit.

Riley had visible injuries and police could not locate a pulse, but they began CPR anyway. A sergeant arrived with a defibrillator minutes later and unsuccessfully attempted to revive the victim.

“Based on the injuries and Riley’s physical condition, I suspected that foul play was involved,” the police report reads.

Clark said it appeared as though she had been killed by blunt-force trauma.

Autopsy results remained pending Friday, but authorities said they were investigating her death as a homicide. Clark said it appeared as though she had been killed by blunt-force trauma.
