A helping hand

Together, they slowly walked up the hill.
Soon Daniela  found her bag.
"Oh, no. My camera's broken," she said.
Tyler saw something and said, "Daniela, come and look at this."
"What is it, Tyler" she asked.

I read "A helping hand".
David was going to the beach with his friends, Daniela and Tyler.
They were riding their bikes to the beach.
But  they went through a gate to Jenkins Beach. It was dangerous way!!
They came across strong dogs. And David went missing!!
What has happened to David??
