The report paints a picture of Haight as a volatile husband concerned about maintaining a facade of perfection throughout the southern Utah community in which they lived, where the majority of residents are members of The Church of Jesus Christ of Latter-day Saints.
The suicide note, and details about how bedding was laid over the bodies, suggest the violence was planned in advance rather than an act of impulse or the heat of passion.
People close to the Haights interviewed by investigators said Haight had lost his job at Allstate Insurance in nearby Cedar City, Utah.
Despite his wife’s wishes and pursuit of divorce, Haight remained living in the family home with his wife, five children and mother-in-law, who was there out of safety concerns.
The report also details how Haight, his wife, mother-in-law and five children were found in bedrooms throughout the family home on the afternoon of January 4 after a neighbour entered and found the bodies.
Police had gone to check on the Haights earlier in the afternoon after concerns about their welfare were reported, but left after it appeared nobody was home.
