Mexican prosecutors are trying to extradite the US suspect in the murder of a North Carolina woman in San Jose del Cabo

Mexican prosecutors said Thursday they had filed charges against a US woman on suspicion of killing another American seen defeated in a viral video.

Prosecutors in the state of Baja California Sur did not name the suspect in connection with the Oct. 29 death of Shanquella Robinson.

But they said they had contacted Mexican federal prosecutors and diplomats to try to get the woman extradited to face charges in Mexico.

Robinson’s death at a vacation spot in the Baja resort town of San Jose del Cabo shocked people in both countries. The video raised suspicions that Robinson may have died at the hands of people she traveled with.

Local prosecutor Antonio López Rodríguez said the case was being treated as a potential murder and an arrest warrant was issued for the suspect. However, the group Robinson was traveling with left Mexico after being found dead in a rented villa.

Prosecutor Daniel de la Rosa Anaya said the suspect was also American but had not identified her.

The FBI confirmed to CBS News Tuesday that it had also launched an investigation into Robinson’s death.

A video, apparently taken at the luxury mansion in San Jose del Cabo, shows a woman, apparently American, beating another woman, identified as Robinson.

The video was posted multiple times on social media sites. A man with an American accent can be heard saying, “Can you at least fight back?” The man didn’t appear to intervene in the beating.

The video raised questions as to why no one intervened in the alleged beatings or why people she was traveling with hit her.

Shanquella’s mother, Salamondra Robinson, said in an interview with CBS News last week that she was initially told by Shanquella’s friends that Shanquella was suffering from alcohol poisoning. But later Salamondra learned there was a fight and an autopsy revealed she had spinal cord and neck injuries.

The autopsy revealed that “her death had nothing to do with alcohol,” Salamondra said.
