Narrative:

While returning to mqy; I made an initial call approximately 8 nm southeast of the airport where I was told to make straight-in for runway 32 and to report a 3 nm final. I backed up the straight in with the ILS 32 even though it was VMC. Upon reaching 3 nm; [I] made the report; in which we were cleared to land runway 32. Around 1;000 ft MSL still on the glidepath; about 1 nm final; received a traffic alert from the skywatch system onboard the aircraft. Being close to landing; I hit the cancel traffic alert since it is normal to get an alert on short final when another aircraft is holding short of the runway. Upon looking back outside; I noticed there was a cessna appearing to finish a right base to final turn same altitude to 100 ft below us and about 1;000 ft in front of us. Slightly shocked that there was another airplane so close; [I] initiated a go-around; side stepping to the right of the aircraft and made a call to ATC. At this time; the aircraft landed on runway 32 and ATC attempted to make contact with the aircraft; [but] the aircraft gave no reply as it taxied across the other runway and into the ramp.recapping the scenario; as pilots flying in controlled airspace such as a class delta; we grow complacent that all aircraft are in contact with ATC. This shows that an aircraft can take a turn early or just not communicate with anybody and come into close proximity with your aircraft. The eyes outside should remain on high alert no matter what airspace you are flying in.
