Oregon Trail Game Question?

I have a question about the Oregon Trail game. I don’t know if it is for the new or old version but I would assume newer version. My nephew said that he was playing Oregon Trail and that in it he was supposed to kill an Indian guard to progress. He didn’t and got in trouble because he put up a fuss about it. For which his family is very proud of him. In fact it started a whole issue on the Oregon Trail and now they are re-writing the curriculum at his school to be more reflective of Native history. Anyhow I know the last part is true about how he put up a fuss in regards to the Oregon Trail (in general not sure about game) and they are re-writing the curriculum. But I don’t know about killing the guard during the game. I tried to google it and couldn’t find anything either way. Can anyone help me out??

Side note: I know I haven’t been around much but I hope you are all doing well!! Just loving life as a new mom :)
