Do I use "Rest assured", "be sure", or "trust" in this context ?
For example: As long as I still don't find his body, I can't rest assured / be sure / trust / that he's really dead. You shot him and he fell in the river. He could have floated to a villager's house and got rescued.

Thank you.

Answer

All three can be used in this context.  The word "still" is not needed in the sentence.

As long as I still don't find his body, I can't rest assured / be sure / trust / that he's really dead. You shot him and he fell in the river. He could have floated to a villager's house and got rescued.

Answer

Not got rescued.  Been rescued.
