Read the following passage from a department policy manual:
"Department General Order 4.15 states: 'All property seized during an investigation must be logged on Form 34-B before the end of the collecting officer's shift.
The form requires the officer's name, the date and time of collection, a specific description of the item, and the location where it was found.
Any currency over $500 must be verified by a supervising officer before being sealed in an evidence bag.'"
Officer Miller seizes a laptop and $650 in cash from a suspect at 3:00 PM.
His shift ends at 5:00 PM.
He immediately has his sergeant verify the cash amount.
According to General Order 4.15, what is the next step Officer Miller is required to take?
