I'm a property manager, and the management company is completely liable here. The elevators I have in my buildings notify an elevator monitoring company, who then call out an elevator maintenance company to get the entrapped people out. When the emergency button is pressed, it also tells the monitoring company which elevator the button was pressed in. The management company was told there was an entrapment, and then they only check two of the three elevators??? Regardless of whether you know which elevator had an entrapment, or if the third elevator is in a renovated area, all elevators should be checked. We don't even allow our building engineers to touch elevators. Only the elevator maintenance company is allowed to maintain the elevators. A lot of bad decisions by this management company to say the least. Horrible. My thoughts go out to this poor man's family during this difficult time.
