If a passenger reports an unattended bag left on a seat, what is the correct protocol for the driver?

1. Open the bag immediately to search for identification
2. Throw the bag out of the window into the bushes to remove the threat
3. Stop the bus safely, do not touch the bag, evacuate passengers to safety, and report to BOCC and the Police
4. Take the bag to the depot lost-and-found at the end of the shift without reporting it
