Who took money from the safe?
Evidence (5)
#1The safe's electronic keypad does not function during a power outage.
#2The safe has an emergency mechanical key override. Only the manager, Yuki, has this key.
#3Ava was at the front desk. The battery-powered CCTV confirms she stayed there from 7:30 PM to 11:30 PM.
#4Marcus was reorganizing the walk-in cooler with a flashlight. Another employee saw him there at 9 PM.
#5Sonia clocked out at 7:45 PM, before the outage. The battery-backed door log confirms she left.
