Narrative:

My aircraft was on a visual approach to 34L at sea. A B767 was about 7 miles behind on visual approach to 34R. After landing my aircraft I exited at taxiway kilo. Usually the tower tells us to 'hold short' or 'cross runway 34R', but nothing was said or heard. I was holding short of 34R and finally I asked the copilot to contact tower and inform them that we are 'holding short 34R,' the tower then told us to 'cross 34R and contact ground. As we proceeded to cross, tower then told us to 'hold our position', but we were already out on the runway, and we saw the B767 rolling out toward us following its landing. We hurried across, and the B767 stopped and cleared at taxiway lima. The copilot said he couldn't see the B767 because of the mixture of ramp, taxi, and other lights, as well as the aspect of the B767. (Straight on). It was late at night, people were probably tired, it was very clear, with no obstructions to visibility. Supplemental information from acn 517135: late arrival into sea. The other aircraft landed before us on the parallel runway to the west (landing north runways that night). After touchdown, speed brakes and thrust reversers deployed and the captain said it looked like the aircraft ahead is crossing our runway. As I continued applying rev and brakes I also noticed that the aircraft entered the runway. I then heard tower give 2 or 3 'hold short' instruction but the aircraft was halfway across at this point. I stopped our aircraft and cleared the runway one taxiway prior to the incursion. After all aircraft were clear of the runway. I heard the other aircraft confirm with the tower that they were cleared to cross before the incursion occurred. The captain nor I heard tower clear the aircraft across the runway. However, we were in the landing flare and touch down when it could have happened. The last 50 ft the autoplt is making 10 foot call outs that could have muted tower's radio call. The captain talked to the tower crew after our gate arrival.

Title: MD-80 CREW XING THE PARALLEL RWY AT SEA OBSERVE A B767 ROLLING OUT ON THE SAME RWY.

Narrative: MY ACFT WAS ON A VISUAL APCH TO 34L AT SEA. A B767 WAS ABOUT 7 MILES BEHIND ON VISUAL APCH TO 34R. AFTER LNDG MY ACFT I EXITED AT TXWY KILO. USUALLY THE TWR TELLS US TO 'HOLD SHORT' OR 'CROSS RWY 34R', BUT NOTHING WAS SAID OR HEARD. I WAS HOLDING SHORT OF 34R AND FINALLY I ASKED THE COPLT TO CONTACT TWR AND INFORM THEM THAT WE ARE 'HOLDING SHORT 34R,' THE TWR THEN TOLD US TO 'CROSS 34R AND CONTACT GND. AS WE PROCEEDED TO CROSS, TWR THEN TOLD US TO 'HOLD OUR POSITION', BUT WE WERE ALREADY OUT ON THE RWY, AND WE SAW THE B767 ROLLING OUT TOWARD US FOLLOWING ITS LNDG. WE HURRIED ACROSS, AND THE B767 STOPPED AND CLRED AT TXWY LIMA. THE COPLT SAID HE COULDN'T SEE THE B767 BECAUSE OF THE MIXTURE OF RAMP, TAXI, AND OTHER LIGHTS, AS WELL AS THE ASPECT OF THE B767. (STRAIGHT ON). IT WAS LATE AT NIGHT, PEOPLE WERE PROBABLY TIRED, IT WAS VERY CLEAR, WITH NO OBSTRUCTIONS TO VISIBILITY. SUPPLEMENTAL INFO FROM ACN 517135: LATE ARR INTO SEA. THE OTHER ACFT LANDED BEFORE US ON THE PARALLEL RWY TO THE W (LNDG N RWYS THAT NIGHT). AFTER TOUCHDOWN, SPEED BRAKES AND THRUST REVERSERS DEPLOYED AND THE CAPT SAID IT LOOKED LIKE THE ACFT AHEAD IS XING OUR RWY. AS I CONTINUED APPLYING REV AND BRAKES I ALSO NOTICED THAT THE ACFT ENTERED THE RWY. I THEN HEARD TWR GIVE 2 OR 3 'HOLD SHORT' INSTRUCTION BUT THE ACFT WAS HALFWAY ACROSS AT THIS POINT. I STOPPED OUR ACFT AND CLRED THE RWY ONE TXWY PRIOR TO THE INCURSION. AFTER ALL ACFT WERE CLR OF THE RWY. I HEARD THE OTHER ACFT CONFIRM WITH THE TWR THAT THEY WERE CLRED TO CROSS BEFORE THE INCURSION OCCURRED. THE CAPT NOR I HEARD TWR CLR THE ACFT ACROSS THE RWY. HOWEVER, WE WERE IN THE LNDG FLARE AND TOUCH DOWN WHEN IT COULD HAVE HAPPENED. THE LAST 50 FT THE AUTOPLT IS MAKING 10 FOOT CALL OUTS THAT COULD HAVE MUTED TWR'S RADIO CALL. THE CAPT TALKED TO THE TWR CREW AFTER OUR GATE ARR.
