Part 4/15:
When Nuno and Malcolm surfaced without Peter, worry quickly set in. They initially assumed Peter had taken another exit to avoid a narrow squeeze. However, hours passed, and with no sight of Peter, they made the difficult decision to submerge and search the tunnels. Time slipped away, and after frantically searching with no results, they were forced to call for help when their air tanks ran out.
The cave diving team that responded faced significant visibility issues due to stirred-up silt. Convinced that Peter would not survive the night and that their efforts would now turn from rescue to recovery, the search was called off temporarily as they braced for the worst.
