On Jun 16 night, about 1:15 am, fire alarm went off from one unknown room on the 6th floor. Front desk person went to there to check, knocked the door where most likely the fire alarm went off, but nobody answered. At about 1:55 am, he opened the door, but the door was latched inside. Still the people inside didn’t respond, looks like unconscious. At about 1:10 am, two police offers came, the people inside the room opened the door. Right before police officers came, the fire alarm stopped. Police officers left at 2:15 am. This made my family hardly sleep for the whole night, which put our next day’s long distance drive in risks.
