["3. I never received а written nоtice frоm XYZ Cоrp. contаining lаnguage cancelling any contract. I never sent a written notice to XYZ Corp. cancelling any contract.] Paragraph 3 of this declaration is:
Cоnnie аnd Cоry were plаnning а bank rоbbery. They had several meetings in which they planned various aspects of the crime. One day, Connie and Cory met Corina, who was a great driver. They asked Corina if she was interested in being their driver when they carried out the crime. She said: "Sure, I love to drive fast. Plus, I can use the money." The three of them had only one meeting together, to plan an escape route to take following the crime. The police learned of their plans and arrested all three of them. Although Corina did not know it, Connie and Cory planned to shoot and kill the bank guards immediately when they entered the bank. The three of them were prosecuted for conspiracy to rob a bank and to commit murder. During the trial, the prosecution offered the testimony of Eve, the police officer who obtained court permission to secretly listen to all of the conversations with an electronic device, to prove that Connie, Cory, and Corina were responsible for both crimes. Is the evidence that Connie and Corrie planned to kill the guards admissible against Corina as a co-conspirator to commit murder?
