You are a detective working for a small-town police department, you have been called to investigate a murder that happened last night. After a few hours of searching the crime scene you found fingerprints and were able to identify who the suspect is. You go to the suspect's house address (with a warrant) and knocked on the door after a while of waiting the door finally opens, the man who opened the door wasn't the suspect. Confused you ask the man some questions hoping to get some information out of him. After a few hours of questioning you get the following information from him.
-The man was a friend of the suspect and he came down to stay and visit.
-The man wasn't aware his friend committed any crimes.
-The man said that when he woke up this morning his friend never came back.
With this information you have, you get a feeling that the man might be helping the suspect get away from the police. However, you don't have any proof that the man was helping the suspect and it could be possible that the man only came down to visit his friend unaware of the crime he would commit.
You have three options
1. You assume the man is innocent and that he was unaware of his friend's crime.
2. You place him under arrest for being an accessory to the crime.
3. Other (If you don't like the other options, explain what you would do in this situation and how you would handle the investigation)
What option would you choose NSG?
