Seeking to find new information to shed light on's activities in the murder of his sons and disappearance of his wife, police armed themselves with a search warrant to comb through a rented storage shed and came out with a DNA treasure of a comforter with blood on it.
Detectives in Pierce County filed in court that the comforter had a stain and was gray-blue-pink in color. The report said the comforter tested positive for blood.
Last Sunday Josh Powell committed suicide after he took a hatchet to his 5 and 7 year old, murdering them in a blaze intentionally started with 10 gallons of gas, after he slammed the door in the face of the social worker who brought the two over for a supervised visit.
The case worker reports on ABC's 20/20 that right after he slammed the door she heard him say, "I have a surprise for you," and almost immediately one of them began crying.
In Dec. of 2009, Josh Powell offered to cook for the family. One of their Latter Day Saints guests said it took him four hours to prepare the meal, and after Susan ate, she went to bed saying she wasn't feeling well even before her girlfriend left the house.
In hindsight the friend said it was completely out of character for her to behave in that way. Some speculate Powell put something in his wife's food and that is also why he passed out the plated up food instead of serving it family style.
Just after the meal, with his wife in bed, Josh took off in the van to take the kids sledding, returning home after 8:00 p.m. Neighbors say they heard the car alarm go off for at least 2 minutes in their garage that same night at around 11:00 p.m. when he told authorities he was preparing to take the kids camping in the freezing temperatures.
The next day when the kids were not dropped off at day care, Susan didn't show up at Well's Fargo where she was a stockbroker and Josh missed his work and didn't call in, friends called the police. When law enforcement showed up at the house, they broke in thinking the family must have died inside from carbon monoxide poisoning.
Instead of finding the family they found two fans blowing on a wet spot on the floor in the Powell's Utah residents. Later when Josh Powell came home from his "camping" trip he told authorities he thought it was Sunday, not Monday.
When at daycare recently, one of the boys drew a picture of their van and told the care taker, "Mommy is in the trunk."
Scrutiny surrounds the case from the fact that Powell was able to see his kids, the fact that he wasn't already in jail, and how the dispatcher handled the emergency call before the house blew up.
Saturday, Susan's parents, Chuck and Judy Cox, are having a memorial service for Charlie, 7, and Braden, 5 at Life Center in Tacoma. The public and media are welcome and a live stream of the service will be available by news outlets.
