Prosecuting Attorneys’ Case Brief [PRINT]

People v. Iago

Steps for the Prosecution

The Law:
(a) First-Degree Murder: Iago’s actions were planned, and Iago knew about the impending murder of Desdemona & instigated it or helped bring it about in some way.

(b) Second-Degree Murder: Iago tried to get somebody else killed (Cassio?), and Desdemona was murdered as an unintended consequence.

(c) Voluntary Manslaughter: Iago said and did the things he did to bring about the murder of Desdemona in a jealous rage, but didn’t plan to say or do those things beforehand. A reasonable person would have to become as jealous or disturbed as Iago under the circumstances for this to be true.

The Law, continued:

California Criminal Law (from

401. Aiding and Abetting: Intended Crimes

To prove that the defendant is guilty of a crime based on aiding and abetting that crime, the People must prove that:

1. The perpetrator committed the crime;

2. The defendant knew that the perpetrator intended to commit the crime;

3. Before or during the commission of the crime, the defendant intended to aid and abet the perpetrator in committing the crime;


4. The defendant's words or conduct did in fact aid and abet the perpetrator's commission of the crime.

Someone aids and abets a crime if he or she knows of the perpetrator's unlawful purpose and he or she specifically intends to, and does in fact, aid, facilitate, promote, encourage, or instigate the perpetrator's commission of that crime.
