CABO SAN LUCAS, Mexico (AP) — Mexican prosecutors have filed charges against a U.S. woman suspected of killing another American seen being beaten in a viral video.

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

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

Robinson’s death at a resort development in San Jose del Cabo shocked people in both countries. The video raised suspicions that Robinson may have died at the hands of people she was traveling with.

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

State prosecutor Daniel de la Rosa Anaya said the suspect was also an American, but did not identify her.

News outlets in Charlotte, North Carolina, reported that the people Robinson was traveling with gave differing versions of how she died, but that an autopsy revealed she died of a severe spinal cord or neck injury.

A video apparently taped at the luxury villa in San Jose del Cabo shows one woman, apparently an American, beating another woman identified as Robinson.

The video has been reposted many times on social media sites. In it, a man with an American accent can be heard saying, “Can you at least fight back?” The man did not appear to intervene in the beating.
