More than 800 paged of court documents also showed that authorities were concentrating their investigation on Susan's husband Josh.
The documents, which contain several redacted lines and pages, provided very few new details into Susan's disappearance or the ensuing investigation of Josh Powell.
But what's clear is that throughout the documents Josh Powell is viewed as a murder suspect.
In December 2009 when Susan Cox Powell disappeared Josh Powell claims he was camping with his two boys.
And Susan may have been with them.
The newly released search warrant shows Josh's son Charlie, told police his mother "had gone with them camping on Sunday and that for some reason she stayed at the campsite and did not return home with them."
“Any time we have a statement from an adult or a child you have to take that into consideration and put it in context and you also have to verify it,” says Sgt. Mike Powell of West Valley police.
But despite telling the public Josh Powell was a person of interest the search warrant shows Josh was at the center of a “kidnapping murder investigation.”
The documents also revealed that Susan feared she was to become a “second wife” of Steven Powell, her father in law.
Authorities in Washington where Josh Powell killed himself and his two sons are even more adamant charges should have been filed.
"Our detectives believe an arrest should have been made a long time ago and charges filed and prosecutors backed that up from what we've learned before these documents were released,” says Sgt. Ed Troyer of the Pierce County Sheriff’s office in Washington. “This information coming to light just adds to the totality of the evidence against Josh Powell."
But Salt Lake's District Attorney says in order to prove capital murder circumstantial evidence isn't enough.
“We don't have a body here, we don't have a cause of death or what the manner of death was and these are the kind of weaknesses someone can attack,” says Sim Gill.
Susan's parents aren't satisfied with the release of all these documents. According to the Associated Press they believe police have many more documents tucked inside their vault. And the Cox family attorney says they will continue fighting for the release of those documents.
Prosecutors and WVC police maintained that the case into Susan's disappearance remains open and active.
Several news agencies have been trying to unseal the case files for months.
Most of the information from the Utah documents had already been revealed in March during the voyeurism trial against Josh's father Steve.
Tuesday's release provided more specific details into the WVC investigation.
