Almost the exact same incident happened in my old congo years ago. A middle aged brother collapsed (a very loud collapse I might add) and died also during the ministry school. While fire dept , police and EMS tried in vain to save this poor man, the meeting continued on without missing a beat.
Most congo members were distracted and visably upset by all of this, however the elders in their infinite wisdom continued on with the meeting without missing a beat.
As a matter of fact the meeting was just finishing as EMS wheeled the dead brother though the crowd covered in a sheet, dead as a rock.
When this brothers family heard about this(he was the only JW in his family) they we very upset by the lack of compassion of the brothers and they refuse to allow the brothers to give his funeral talk or have the service in the Kingdom Hall.
