I have slightly modified a puzzle attributed to H.P. (a.k.a. Caliban).
One of five people is a murderer.
Here are their statements:
Bernie: Becky didn’t do it.
Benny: Betty did it.
Bella: Becky is innocent.
Betty: Becky did it.
Becky: I did not do it.
Can you identify the killer?
Given k people, including the killer, lied – provide your answers and reasoning for all possible values of k.
