Aircraft Y landed on Runway 22L; I told him to contact ground. Aircraft Z was trailing behind and cleared to land 22R. I hear ground control give instructions to hold short 22R at B for Aircraft Y. About a minute later I hear ground control talking to another aircraft; Aircraft X to taxi and hold short 22R at Runway 11. I see Aircraft Y hold short Runway 22R. As I am watching Aircraft Z land; and during his landing roll; I hear the supervisor behind me say 'Tell him to stop' to ground control.I look and see Aircraft X still rolling at Runway 11 past the hold short line for Runway 22R. At this point I can't do anything. Aircraft Z is a student pilot; he is already slowed down too much to take back off and Aircraft Y is on his left. Aircraft X was just about to get on the runway; but stopped right before. Aircraft Z pass the other aircraft and rolls to the end. If ground control didn't yell at the pilot to stop; the two aircraft would of hit.Hold short was given to all the aircraft; I don't know if they read back all holding. But; I do know that the holdings were given. This was just a pilot that I don't think was paying attention even though he was given the correct instructions.
Was taxiing from north ramp area to Runway 22L. The quickest route via Taxiway L was NOTAM'd closed (among others) due to construction. Cleared to taxi on Taxiway F hold short of B. There was Aircraft Y on B holding short of 22R on the other side of 22R; which blocked that taxi route to 22L. Approaching B recleared to cross B on to closed Runway 29; left turn; hold short (non-standard marking) of 22R for eventual taxi continuation to 22L. Approaching 29 on F; I looked left; then right; to make sure no conflicting traffic; then made left turn on to 29. As I made the turn; I looked up and to my left to check for traffic landing on 22R. I saw Aircraft Z on about a half-mile final for 22R. Ground said Aircraft X stop at the same time I saw Aircraft Z. I came to an immediate stop and saw that I had crossed the temporary hold-short marking for 22R on 29.About 15-20 seconds later Aircraft Z landed on 22R and crossed in front of me. I couldn't remember if I had read back hold short of 22R or hold short of 22L. After a few seconds; I was informed of a possible pilot deviation and told to be ready to copy a phone number for the tower. I replied that I was in a critical phase of flight and would call back for the number before takeoff. I also needed time to settle down from all of this. I received further clearance to cross 22R on 29; turn left on J; taxi to 22L. This was done without further problems. I reached the run-up area for 22L; pulled over; and contacted ground for the phone number. I also asked how long I had to call since I was ending up in [destination] and this would be a long day. The reply was as soon as possible.Contributing factors were numerous taxiway and runway closures due to construction. This has been going on for an extended period of time. I listened to ATIS and copied the closures and other NOTAMS. This is my home airport; so the construction was not new to me. Also the flight was going to be long with a fuel stop; and arrival weather considerations in [destination state]. This possibly distracted me from the non-standard taxi to 22L and ending up thinking hold short of 22L instead of 22R. I don't feel I was being rushed; but was taking an adequate amount of time while taxiing.Holding short of a runway while on a closed runway was definitely non-standard. I probably should have held short of B as originally cleared; as this would have kept me off of 29 which would definitely have kept me short of 22R. Also in approaching 29; I was more concerned with looking up for possible traffic conflicts; than looking down for non-standard markings. Seemingly small things; but they added up. Maybe I was starting to get overloaded and should have taken smaller steps in the taxi process.
Lafayette Tower Controller and taxiing aircraft pilot reported a runway incursion because the taxiing aircraft went over the hold line.
