Susan intentionally shot a hand gun to kill Mike, but missed.  Later that month, Susan, who still wanted to kill Mike, was driving to work and  hit another car while putting on lipstick.  Mike, a passenger in that car, was killed.  Could Susan be convicted of murdering Mike?  Why or why not? This is a question about murder, NOT negligent homicide.
