No, not specifically related to religion or area traditions. Given she died in Idaho, lived in Idaho, worked in Idaho at two Idaho schools prior to death, it was strange to me--maybe only to me--that the funeral wasn't here for people to grieve near her open or closed casket first. Then perhaps another service in Utah for the former friends and family that resided there before interment. It just felt rushed without the opportunity for so many who knew her to have closure. It was magnified by Chad's moving out immediately. Then we have the hindsight of all the other facts we know about this combined case.
That is interesting. I have been to many LDS funeral services, and they are full day affairs, even 2 days.
Viewing, the night before, then the next day, another viewing, time to gather with the family, a full church service, memorial, trip to the cemetery, short service, back to church for Relief Society luncheon, or at home, depending. (Side note, best food, ever...usually ham, "funeral potatoes, rolls, jello salad, cakes).
Generally, LDS funerals are lengthy and filled with family members, church members, neighbors.
Interesting, that Tammy's funeral was brief.
