Mexican prosecutors said Thursday they have opened an investigation into the death of an American woman who appeared to be beaten in a video that has gone viral. Prosecutors in the state of Baja California Sur said in a statement that they are investigating the death of a woman they identified only as a foreigner at a resort town in San Jose del Campo. A state official who was not authorized to be named confirmed the victim as Shanquella Robinson. The official confirmed that the group he was traveling with had left Mexico. A video apparently filmed at a luxury villa in San Jose del Campo shows a woman, apparently American, hitting another woman. The video has been reposted many times on social media. In it, a man with an American accent is heard saying “Can you at least fight back?” The man did not appear to intervene in the beating. Prosecutors said police found Robinson dead in the villa on October 29. Charlotte, North Carolina’s Queen City News station published a report stating that Robinson died of a severe spinal cord injury. Mexican officials said they could not confirm the cause of death because it was part of an ongoing investigation. The video raises questions about why no one intervened in the alleged beating or why people she was traveling with would have hit her.
