To KIll a Mockingbird chpt 24-26

In the story To Kill a Mockingbird everything is becoming so exciting even though Tom Robinson is found guilty. I believe that Tom shouldnt have been found guilty. Everybody  knows that Mr.Ewell had hurt his daughter but because he is a white man vs a black man nobody will say anything. Now that Tom Robinson is guilty he goes to prison and tries to escape but then is shot and killed.Atticus is very sad because of what happen to Tom Robinsn.  Then Bob Ewell says that their are  still two people left to take down after Tom Robinson dies. Who are those people now that Tom Robinson is dead?
