Now it's being reported as just smoke from a motor in the elevator itself:

An apparent faulty motor temporarily trapped people inside an elevator at a Phoenix high-rise building Monday morning, causing smoke in the elevator shaft and triggering a big response from firefighters.
A group of people became stuck in an elevator on the 20th floor of the a multi-business building at 3838 North Central Avenue in the City Square around 9:30 a.m., said Jay Arthur, Phoenix fire department spokesman.
Smoke was reported in the eighth floor elevator shaft and the building was smoothly evacuated without panic, Arthur said.
There was no reported injuries or damage to the building, Arthur said. No one was injured and there was no damage to the building, Arthur said.
The people trapped in the elevator managed to open the door themselves and left the building, Arthur said. Officials believe that the elevator stopped due to a motor-related equipment failure.
The property manager reported that there were between 500 and 600 people in the building at the time of the evacuation.
Evacuees applauded the firefighters as they exited the building and made their way back to the fire trucks.
Evacuation supervisors had no comment.
3838 is a different tower than the one I posted above. The complex is on the left here:
