Shanquella Robinson's mysterious death in Mexico smells like a set up to her father ... he tells TMZ he believes his daughter was attacked as part of a diabolical plan.
Shanquella, who was from North Carolina, was found dead last month in her room in Los Cabos ... where she was vacationing with a group of friends. Her parents say the friends told them the 25-year-old died of alcohol poisoning.
However, her parents now say Mexican authorities have told them Shanquella died from blunt force trauma to her neck and spine -- and a brutal new video does indeed show a woman beating up Shanquella while she was naked in a room.
This is a really horrible story and we pray that she receives justice sooner than later.
