Brenda Wright Lafferty

Brenda Wright Lafferty, wife of Allen Lafferty and mother of their infant daughter, Erica, was one of the people named in Ron Lafferty’s purported removal revelation. On July 24, 1984, Ron and his brother Dan Lafferty entered Brenda’s apartment in American Fork and murdered her and Erica. Their deaths lay at the center of the book’s account of religious claims turned into violence—and of the later dispute over how much each brother had done.

Family and Forewarning

Brenda was part of the Lafferty family through her marriage to Allen, Ron and Dan’s younger brother. The danger to her and Erica had been anticipated: Bernard Brady’s affidavit named both among ten people whose lives he feared were at risk. Yet Brady did not alert the police. He put the affidavit in a desk drawer, preserving evidence that he had foreseen danger without acting to prevent it.

The warning did not remain only in that document. Dan later told Allen that God had commanded the ritual murder of Brenda and Erica, and that he and Ron intended to carry it out. Allen was shocked and questioned why the command would include Erica, an innocent child. The warning made the murders foreseeable to people around the brothers, but it did not stop them.

The Murders and Conflicting Accounts

On July 24, 1984, Ron and Dan went to Brenda’s apartment in American Fork. The brothers’ later accounts differed over who wielded the knife. Dan said he killed both Brenda and Erica; he also described himself as the person who had used the knife when recounting events during the drive away from the scene. Chip Carnes, however, testified that Ron had described his own violence against Brenda and said he handed the knife to Dan. Dan disputed much of Carnes’s account, though not its central claim that Dan killed Erica.

The disagreement over the specific acts did not make the brothers’ shared role uncertain in the book’s telling. Both were inside the apartment when the murders occurred, and the narrative characterizes the killings as a joint undertaking for which Ron and Dan were equally culpable. Brenda and Erica were dead regardless of which brother inflicted a particular injury; the disputed testimony instead became part of the struggle to establish each man’s responsibility.

Trial and the Record of Her Death

Dan’s account grew more consequential by the mid-1990s, when he became willing to speak openly about what had happened. His testimony placed Ron inside the apartment and described Ron’s participation, undermining Ron’s earlier claim that he knew nothing of the killings. The narrative presents Dan’s version as broadly credible while preserving the distinction between his account and Carnes’s testimony about who used the knife.

Ron’s 1985 convictions were later vacated by the Tenth Circuit because the court found that the trial had used a faulty standard to assess his competence. That ruling required a new trial if Utah wished to prosecute him again. The reversal changed the legal course of the case, but it did not undo the murders or resolve every dispute about the brothers’ respective actions. Brenda’s story is thus also carried through a contested evidentiary record: advance warnings that went unreported, a surviving brother’s later testimony, and incompatible descriptions of the same crime.

Character and Narrative Significance

The evidence gives Brenda little space as a speaker or actor; it identifies her through her marriage, motherhood, and victimization. The narrative nevertheless describes her as a big-hearted young woman, a characterization set starkly against the brothers’ decision to turn an asserted command into lethal action. Her death is not presented as an abstract consequence of religious extremism: the affidavit, Allen’s alarm, and the later testimony all point back to two specific people whom others knew were in danger.

Brenda’s inclusion among those named in Brady’s affidavit also sharpens the contrast between foreknowledge and intervention. A warning existed, and Dan disclosed the intended violence to Allen, yet neither fact protected Brenda or Erica. The book follows the consequences beyond the murders, through the brothers’ conflicting accounts and Ron’s overturned convictions, while keeping the decisive fact in view: both brothers participated in the killing of Brenda and her daughter.
