Swapp, 46, will appear again before the board in September 2012, after having served seven years of his 1- to-15-year manslaughter conviction.
A "rationale" sheet, in which the parole board marks mitigating vs. aggravating factors, shows Swapp has accepted responsibility, has expressed remorse and is motivated to change, and has had few disciplinary problems while in prison.
On the aggravating side, Swapp is listed as an "organizer" or "leader," he is considered on object of "community fear" or "condemnation," and the crime is listed as intentional or premeditated.
The manslaughter conviction stems from the fatal shooting of Lt. Fred House on Jan. 28, 1988, by Addam Swapp's brother-in-law, John Timothy Singer.
The death of House ended a 13-day standoff between police and a dozen Singer-Swapp family members, who had barricaded themselves inside a home in Marion.
Prior to beginning his state sentence in 2005, Swapp spent about 17 years in federal prison for detonating 87 sticks of dynamite inside the LDS Church's Kamas stake center, according to a parole board press release.
Swapp apparently believed the stake house explosion would bring down The Church of Jesus Christ of Latter-day Saints and resurrect John Singer, Swapp's father-in-law, a fundamentalist Mormon who was shot and killed by police officers nine years earlier.
During a March parole hearing, Swapp told board member Clark Harms that he believed Singer was unjustly killed and never afforded justice from the court system.
But Swapp said he was sorry for blowing up the Kamas stake center and for the events leading to the death of House.
Swapp said he has asked for God's forgiveness and now wants to follow the example of Jesus Christ, but he still ascribes to fundamentalist Mormon beliefs.
He vowed, however, that he would never repeat his crimes.
Swapp has been incarcerated in an Arizona prison to avoid potential conflicts with Utah.
