So sorry to hear that. Not knowing them it's hard to imagine, but for you knowing them closely it must be very difficult to deal with. Not to mention what a difficult loss this is for each family involved.

Again, so sorry to hear the news... I wish there was something we could do... As others have said, were glad you were not involved in the accident itself, but know it will be difficult for you and the families to cope with the loss... we wish you and their families all the best.
