Mexican authorities issued an arrest warrant for the woman suspected of assaulting Shanquella Robinson in San Jose del Cabo last month.

Shanquella Robinson, 25, left North Carolina on vacation with friends on Oct. 28, but was dead 24 hours later. Her parents first believed she died from alcohol poisoning after receiving a frantic call from her friends.

However, Mexican authorities later revealed that a spinal cord injury, not alcohol poisoning, caused Robinson's death, prompting an internal investigation.

Mexican officials have not named the suspect but did confirm she is a U.S. citizen.

Attorney General Daniel de la Rosa told ABC News, "There is already an arrest warrant issued for the crime of femicide to the victim's detriment and against an alleged, responsible for these acts, a friend of hers." He also said Wednesday, "The death did not result from a "quarrel," but from direct aggression that this person made."

"We are already carrying out all the relevant procedures, both the Interpol file and the extradition request," he said.

Following the autopsy results, Robinson's parents called on the FBI to investigate, believing foul play was involved.

An unauthenticated video circulating on social media later surfaced and appears to show Robinson being beaten inside a hotel room. In the video, an off-camera voice says, "Quella', can you at least fight back?" A female can also be seen being repeatedly slammed to the floor and punched in the head while trying to escape her attacker.
