Assassination Trivia

[Anita]

This probably isn't what you are looking for but I have an article saved from the LA Times on a much broader topic. It's written by Susan Moeller back in 2007. She talks about the hanging of the Lincoln conspirators and mentions that after the hanging the crowd outside the prison celebrated with lemonade and cake.

Or was there testimony at the trial by a witness who saw Mary Surratt serve lemonade and cakes to one of the conspirators?
