Where is he?

You will find Inigo in Riften Jail. He's next to Sibbi Black-Briar in the first cell on your left.

Keep an eye out for notes referring to Inigo on your travels.
If your character needs a reason to visit the jail they may give you the excuse you require.
Inigo is technically not a prisoner.
You don't have to pick the lock to his cell.
Read the letter on the table on your way in to learn more.
