Busted!
Great use of the camera.
Looks like you have your work ahead of you closing off some entrance, when you know the critter is outside (unless it just walked in through the open garage door) or set a trap in the attic. The unfortunate thing with trapping them is that they can really hurt their front paws, wrists and forearms while trying to escape from a trap. Trying to reach something, unlock something, dig out, ... I felt terrible for one little guy, while trying to get whatever was tearing up the lawn or digging under the deck, chewing on wiring and plumbing etc. For that reason I've thought about lining my critter trap on the outside with small square rabbit wire, so they can't stick their paws through anywhere and scrape themselves; and put a bit of a wooden bottom in, so they can't try to dig out. Plus they go a little wild when you go to move trap with them in it. Dark thick cloth helps.
Anyway, we also get a lot of critters walking through and doing some expensive damage sometimes. Too much too mention but a couple notable ones were one hungry raccoon coming inside the house - and leaving fortunately - through a cat flap. A family of porcupines under the deck. A skunk taking up residence in the garage for a few weeks, under a shelf, tearing up a bunch of stuff left & right at night, destroying garage door seals, etc. Took a while to figure it out and what fun it is to try to chase a skunk out of a garage! They don't run for an open space or open door in daylight!
Since then I have a critter (hunting) cam and a couple foscams, which would help. Certainly will put a cam to use the next time something is up!
