To a point... because that garage closed at 1:00am on the night Hannah went missing. But that doesn't disallow a number of related possibilities, such as Hannah and the POI walking through that garage, and/or the POI's car being parked on a street adjacent to the garage. And then either a camera captured his license plate or a witness (as yet unreported) did so. That's really all it would take to get probable cause for a search warrant on the vehicle (and properties associated w/ the vehicle, i.e. the address on the vehicle registration.)
