Narrative:
Aircraft Y short final runway 10L with aircraft X on landing roll (touch and go). Aircraft X became airborne at echo intersection (4800 ft). Aircraft Y (BE20) crossed the threshold with a landing clearance. Local control (local control) had previously informed aircraft Y to be prepared for a go-around. I suggested runway 10R to local control and then said 'you should send him around' when local control allowed the aircraft to continue. After separation was lost and local control was relieved a few minutes later; I said to the local controller 'you know that a BE20 is a CAT III; right?' local controller said 'oh; close enough'. I should have been more forceful in telling the local controller to send the BE20 around. Local controller should know aircraft type/categories.
