West Valley police search Washington home of Susan Powell's husband

"I don't think I can describe the roller coaster that goes with something like this," he said, adding that news of the search warrants was "an upper" on the coaster ride.

"I hope this will lead to some new information and closure at some point," Jennifer Graves said.

Debbie Caldwell, a friend of Susan Powell who often watched the couple's two boys, said she doesn't know what police may be searching for, but is glad someone went to the home.

Sunday night, she and five other women who knew Susan well compared notes and hoped for further action in the case.

"We all shared our brief snippets of what we knew about Steve (Powell) and I was hoping they would at least go in and check things out," Caldwell said. "(Susan's) private journals, all those things, who does that kind of stuff?"

Still, Caldwell said her primary concern is for the couple's children, ages 4 and 6.

"We'll just have to wait and see," Caldwell said. "I'm just worried about the boys. We’ll be praying."

The ongoing feud between Cox and Steve and Josh Powell has also captured the attention of the national media. The three men appeared on national news shows Wednesday and Thursday, including ABC News and the "Today" show.

A Washington judge recently ordered Cox and Josh Powell to stay at least 500 feet away from each other.

Thursday, Josh Powell repeated claims on the "Today" show that Cox has "just been going out of his way to bring craziness into our lives." In court documents, Josh Powell said he feared his father-in-law was going to kill him because he blames him for the disappearance of his daughter.

Cox told the morning TV program that he has never threatened Josh Powell and that the focus right now should be on finding his daughter. He also noted that the attacks from the Powells have been increasing.

Perhaps the most eye-raising comments came from Steve Powell, who claimed he was in love with his son's wife.

"Susan was very sexual with me. She was very flirtatious," Steve Powell told ABC News. "We interacted in a lot of sexual ways because Susan enjoys doing that."

When asked if he was in love with Susan Powell, he said: "That's pretty likely, yeah, I think so, and there's no question in my mind that the feelings were mutual."

Steve Powell made similar statements on the "Today" show. "She was very flirtatious and very sexual with people," he said. "Frankly, sometimes I wish we had done a little more than we did."

"I see these attacks as outrageous, cowardly, despicable and not believable in any way and I trust that the media and the public can see right through this," Cox told the "Today" show. "Basically he's trying to blame the victim and my daughter is the victim here."

Friends and family of Susan Powell have recently come forward to say Susan had told them that it was the father-in-law who made inappropriate advances on her. She insisted on moving to Utah because she "despised" her father-in-law and had forbidden him from entering her West Valley home.

Jennifer Graves said her father's behavior was something she directly discussed with Susan Powell before her disappearance. Steven Powell made his daughter-in-law feel uncomfortable and possibly afraid.

"There was a certain amount of fear, so she wanted to put distance between her and my dad," Jennifer Graves said.

Many commenters on the Friends and Family of Susan Cox Powell Facebook page had strong reactions to the interviews.

"I'm sorry to say but Josh Powell and his father are sick! How can they do this to the Cox family and even to Susan's and Josh's boys?" one person posted. "I really hope the West Valley police are checking into Steven Powell. He is one strange and sick man."
