Read the following example case and answer the following questions.
A 7-11 was robbed last night at approximately 9:00pm. A masked individual entered the convenience store with a gun, waving it in the air and demanding the cashier give him the money from the register. The cashier complied with the request and gave the man 600 dollars from the register. Witnesses reported seeing a suspicious looking man about 6 feet tall wearing an orange jacket, black hat and a lion tattoo on his leg. Police arrested Adam Green as a suspect a day later. Adam has a previous record of petty theft but claims he was at his friend’s house for dinner. Adam’s friend confirmed that Adam was with him at dinner at the time of the robbery. Adam was identified by an eyewitness based on his height and jacket. Adam has a lion tattoo that matches the description, but the design is not unique to him. The gun was not found.
