At one point, he asked the police if he was a suspect in his wife's disappearance.
"Have I told you you are a suspect?" the detective responded.
"Well, it's felt like it a few times," Powell said.
Toward the end of the interviews, police read Powell his Miranda rights -- a warning against making self-incriminating statements -- and Powell declined to answer any more questions.
"Yeah, let me think about it for a couple of days," Powell said of his decision about whether to keep talking.
"Your wife is missing, Josh, and you want to think about it for a couple of days?" a detective replied.
"I've already answered everything," Powell said.
Powell insisted on having a lawyer before continuing the interrogation with West Valley City police, who never questioned him again for the rest of the search, which lasted nearly three years. Powell continued to deny any involvement in Cox Powell's disappearance until his death in February 2012.
