you are a detective in the local neighborhood. Four windows have been broken: the school's window, Mrs. Smith's kitchen window, Mr. Brown's car window, and the police officer's window. The four suspects are Alex, Collin, Josie and Raymond, and we know that each one of them broke a single window
I did not break Mrs. Smith's kitchen window, and I did not break Mr. Brown's car window.
Alex did not break the school's windows.
I know what happened. Collin broke Mrs. Smith's kitchen window and Alex broke the police office's window.
I broke Mr. Brown's car window or the school's window and I am sorry.
You know that one of the suspects is a liar and three of them are telling the truth. Who broke Mrs. Smith's kitchen window?
