　Moreno, Stanley, and 23 other students from Westfield State College were on vacation in Acapulco, Mexico. This was the last night in the hotel. It was 4 am, Moreno and Stanley came back from a party.

　　Just as Stanley went to sleep, he heard loud noise outside. From the balcony (陽臺) of their fourth-floor room, Moreno and Stanley saw black smoke out of one window and heard people shouting.

　　Moreno ran out into the corridor and began knocking on doors and shouting, "Fire!" After that, he went upstairs in a hurry to tell other people. At the same time, Stanley was downstairs helping people get through the smoke-filled room. There he joined forces with Nalewanski, a 21-year-old boy who had a room on the second floor.
