Gregerson grew up the seventh of eight children
in a Mormon family in Orem, Utah. According to his older brother
Spencer, Gregerson "just seemed like a lazy person", and Spencer
does not recall him graduating from high school.
He was previously employed by Radio Shack and a
number of temporary staffing agencies. He was convicted of assault
in December 2004 for punching his mother-in-law in the face, and
other domestic violence incidents with his wife Catherine have been
reported.
Norton murder
Gregerson resided in a duplex in downtown Salt
Lake City that shared a yard with the house that Destiny Norton and
her parents occupied along with a number of other people who were
acquainted with each other from the drum circle scene in downtown
Salt Lake City.
Norton was reported missing on July 16, 2006. The
case earned national press attention, and police launched an
investigation, and suspicion eventually focused on Gregerson.
Police search warrant affidavits revealed that
Gregerson consented to an FBI polygraph test on July 24, 2006, and
later signed a full confession, telling authorities he had been
keeping the girl’s body in his basement for eight days.
Gregerson reportedly told FBI agent Steve
Fillerup, the polygraph examiner, that he had been planning
Destiny’s abduction "for some time" and that he had "made written
plans" for the crime. Gregerson reportedly lured the girl into his
row house unit, where she “panicked and began to scream", then "went
limp" after he gagged her.
Gregerson carried the girl’s body into his
basement and sexually assaulted her. He kept the body in a plastic
container, and later purchased supplies to mask the odor coming from
the basement.
Gregerson was charged with kidnapping and
aggravated murder on July 27, 2006. Gregerson waived his rights to a
speedy trial, and later waived his rights to a preliminary hearing
which had originally been scheduled for October 3 and October 4,
2006.
In a plea bargain to avoid the death penalty, he
plead guilty to capital murder and child kidnapping on December 4,
and was sentenced to life in prison without parole for the murder,
and fifteen years to life for the kidnapping. The sentences will be
served consecutively.
