No...there is no way if that guy was a JW that he would have NOT said Jehovahs name like 20 times during that prayer.
They might have a private talk in a funeral home someplace done by a JW brother. As long as its not in a hall. We had a man commit suicide who was a DAd JW and they did have a talk in the hall. His body was not present. But his SON who was in his early 20s and a JW, gave a talk.
I thought it was odd...but I think they did it for the benefit of the JW family who were still with us.
