The perfect murder

Elaine and Ivy are two friends who work for the schools newspaper. Looking for new juicy gossips, Elaine comes across a file in the schools library that reads:

CASE CLOSED.

Curiously, she opens the file and reads it. When Elaine finishes, she knew she had to show it to her best friend.

- Ivy! I found something! Come check this out.

- What did you find?

- This case is perfect for our news.

- Are you sure we can decipher it?

- Yes. You and I are the perfect duo. If somebody can solve this case, it's us.
Here is the case information:
