To figure out whose bag it is, read the yearbook.

The yearbook says Harrison was the captain of the basketball team. The bag is in the shape of a basketball, so we can infer the bag is Harrison's. Can you find any clues about what Harrison might use for a 3 digit password?

There is a printout of "SecureLogix Security Questions" for Harrison (from Part 2). One of the account recovery questions has a 3 digit answer format (Harrison's lucky day).

To figure out Harrison's lucky day, read the yearbook carefully.

Pay special attention to the autographs page (in the yearbook).

One of the autographs mentions that Harrison won 10k on a scratch ticket in grade 10 on April Fool's day.

• The basketball bag is Harrison's, and the code to unlock it is Harrison's lucky day (in dmy format).
• In grade 10, Harrison won $10,000 on a scratch ticket on April Fool's day (mentioned in the yearbook autographs). This is Harrison's lucky day.
• The yearbook is from 2002, and autographs reference Harrison graduating. If Harrison graduated in 2002, he would have been in grade 10 on April 1st, 2000.
• Translated into dmy format, Harrison's lucky day (April 1st, 2000) is 140. The password to unlock the basketball bag is 140.
