Caught in a bizarre family love triangle, Timothy John 'TJ' Brewer, 33, allegedly found his wife Logan Rae Brewer 'on top of his dad', respected Moab fire chief Wesley 'Corky' Brewer, after they had dinner at TJ's Utah home on July 11.
Furious at their love tryst, TJ 'backhanded' his wife and pointed a gun at her, before 'pistol whipping' his father, who later stabbed himself.
According to police documents published by TPM, the trouble started when Logan went upstairs after dinner - during which they had all been drinking - to put one of her children to bed.
Realizing he was alone in the house, TJ, a 12-year veteran of the Moab sheriff's office, went upstairs to find his wife.
Deseret News reports Brewer told investigators he found his son's bedroom door locked, got into the room, and 'lost it' when he found his father and wife in bed together.
