We need to establish an alibi. If there's anyone who can verify his whereabouts throughout the week, that wouldn't be bad, but if we can find out where he was and whom he was with when the spell broke down, that would be great. The guy we're looking for was fighting the attack victim at the time, so if we can get his schedule as close to then as possible.

And the killer had abilities. You might have to read his mind, but if we know he didn't have speedster abilities at the time, that's enough to clear him.
