Shanquella Robinson, the 25-year-old hair braider from North Carolina who was found dead in her hotel room while on vacation with friends in San José del Cabo, was a victim of "direct aggression" by a female friend of hers, according to Mexican authorities.
On Thursday, the attorney general for Mexico's Baja California Sur, Daniel de la Rosa Anaya, said that an arrest warrant was issued and that the extradition process was underway for the suspect in the death.
The death did not result from a "quarrel," he said, "but instead a direct aggression."
The suspect has not yet been named.
Initially, Robinson's friends had told her mother, Salamondra Robinson, that her daughter had died of alcohol poisoning.
“They said she wasn't feeling well. She had alcohol poisoning,” her mother told WJZY. “They couldn't get a pulse. Each one of the people that was there with her was telling different stories.”
Then, last week, a video surfaced that appeared to show Robinson being beaten in a hotel room. In the clip, Robinson is knocked to the ground as a woman repeatedly hits her in the head. The person filming the video can be heard saying, "Can you at least fight back?"
The FBI in Charlotte confirmed to BuzzFeed News last week that they had been in contact with Robinson's family and were aware of the video circulating online.
When the death certificate was released, it showed that Robinson's death was caused by a severe spinal cord injury and atlas luxation (a form of severe neck injury).
On Tuesday night, ABC News reported that Robinson may have received care from a medical professional several hours before authorities arrived and found her dead. The medical professional reportedly told Robinson's friends that she was drunk and that they should take her to a hospital, but they allegedly declined to do so.
In response to the news that an arrest warrant had been issued, Robinson's mother, Salamondra, told ABC News on Wednesday, "I feel so good, that's a good feeling. That's what we have been waiting for, for someone to finally be held accountable and arrested.
"I just can't wait for justice to be served," she added.
BuzzFeed News has reached out to the FBI, US State Department, and Mexican authorities for comment.
