Martha Sorenson, 75, and her husband Robert, 81, were found dead in their Sanders, Arizona home on the evening of July 1, 2017, after family members requested a welfare check. Deputies from the Apache County Sheriff’s Office forced entry after seeing a bedroom window that appeared struck by gunfire and discovered both victims with multiple gunshot wounds.

Investigators identified 51-year-old Garry B. Wilckens, the boyfriend of the Sorensens’ daughter Susan, as a person of interest. Officers learned there had been a domestic incident involving Wilckens and Susan on a highway the same day, and neighbors reported seeing the couple arguing outside the Sorenson home before hearing shots. A statewide manhunt followed; Wilckens was captured in Mesa, Arizona on July 7, 2017, and extradited to Apache County to face murder charges.

Family members suspected jealousy and possessiveness as possible motives. Anyone who knew the Sorensons, Susan, or Garry Wilckens and has information relevant to the case is asked to come forward.
