Is it "me" or "I" and why? [duplicate]

Simple rule: If it's the subject of the verb, use I. Otherwise, use me.

In the sentences you provide, I is indeed the subject of the verb found.

The other pronoun at the end, however, is not the subject of a verb, so it should be me.

(Probably this question will get closed because it's too basic, but this is the simple answer.)
