Pierce County sheriff’s investigators found a comforter stained with blood inside a storage unit rented by Josh Powell but further tests are needed to know what kind of blood it is and who it belonged to.
“None of that can be answered with what we’ve done (so far),” Pierce County sheriff’s spokesman Ed Troyer said.
The stain on the gray-blue-pink comforter had some properties of blood. It’s been turned over to West Valley City police.
“They will determine if it is relative to their case,” Troyer said.
Investigators also found kids’ blocks, toys, clothes and picture frames in the storage unit, according to a search warrant returned this afternoon.
The kids items were given to the Cox family.
Pierce County sheriff’s detectives searched the Sumner storage unit Tuesday, two days after Powell lit his Graham-area rental home on fire, killing himself and his two sons, 7-year-old Charlie and 5-year-old Braden.
The boys had gone to the home for a scheduled, supervised visit. After the boys went inside, Powell shut the door on the case worker who was to supervise the visit.
Detectives have been retracing Powell’s movements and conducting related searches in the days since. Powell went to the Sumner storage shed the day before the house fire, the search warrant states.
