Telling someone
Kim had to call the police of the park rangers to let them know just what she found. Maybe it would be a great help to them if she found the keys to the missing person’s car. She made the phone call and told the authorities everything. They thanked her for the information.
After that, there was not much that Kim could do. She told them where she had found the keys and perhaps this person had slipped and fallen off of the cliff. Now she could just go back to her regular life and hope that they found the body of the unfortunate hiker.
