The Officers Assumed
Cops had looked through street cameras. They had noticed Dave circling the dog and interacting with him as well as the drain every day. They had no leads at the moment, but they didn’t want to reveal what they had discovered inside the sewer. When Dave questioned them about it, they turned pale.
They Needed Information
They needed some leads and asked him to walk them through his day. They only had one option because Dave had alerted the emergency services. They needed to learn everything they could. This day, Dave began outlining for them.
