Learn English – What are some other ways to say: “I expected that to be the case.”

I need to know other natural ways to say: 'I expected that (=what you just said) is the case.'

Example:

Jessy: Do you know who left that half-eaten sandwich on the table?

Edd: Robert did. I saw him eating there last night, and he was the last person to eat here.

Jessy: I expected that to be the case. This guy is so lazy!
