As Lori and Chad Daybell move closer to trial, Tammy Daybell's death is back in center stage.

Tammy Daybell's death is initially ruled natural causes. The seemingly healthy 49-year-old is training to run a 4K race, but Chad Daybell reports that his wife is dead in the bed beside him one morning.

The family refuses an autopsy, but as bodies seem to pile up around the newlywed family, Daybell's body is exhumed. Although authorities have not publicly released her cause of death, Tammy Daybell's children say she died of asphyxiation.
