As you discerned from their name, they specialize in keeping accused criminals off death row. On your first day at the firm, they ask you to write a memo summarizing their three easiest cases of the month. Case 1 involves a 17 year-old boy who is accused of felony murder, a capital offense in that state. Case 2 involves an accused murdered whose IQ score is 62. Case 3 involves an individual who raped and murdered a child. Answer the following questions about the report you will craft to summarize these cases.
