Sammy Is the Mayor of Friendlyville and Has Been Siphoning

Sammy is the mayor of Friendlyville and has been siphoning money from the Boys' and Girls' Club over the past six years, amassing a tidy sum of $58,000. When the scam comes to light, investigators interview Sammy, who disavows any knowledge of the crime, blaming the allegations on political enemies. John, the deputy mayor, who has known of Sammy's illegal behavior for some time, provides a complete picture of Sammy's crimes to investigators. Both John and Sammy are placed under arrest, but not before deleting as many emails about the subject as possible.

A) The defendant(s) who would be guilty of committing perjury would include: ​
B) Sammy, because he lied to investigators.
C) John, because he deleted emails relevant to the case.
D) both Sammy and John because they both had knowledge of the stealing.
E) neither Sammy nor John because the trial had not yet started, and they had not yet testified under oath.
