Sounds like they had the funeral too soon. Should have waited until this weekend to hold the memorial service pep rally.
Jewish custom states that the burial must be at the first possible moment.....Since Friday afternoon was not possible due to the crash and Saturday is not allowed, my guess is that the funeral was immediately after the autopsy....which meant Monday. And it was private, without media.
What followed was a travesty that the families will live with forever. Whether it was their own idea, doubtful, or they exploited the tragedy is immaterial....they made a most disrespectful sham out of their father's death.
