SALT LAKE CITY (ABC 4 News) - Steve Powell won't talk.
He's facing voyeurism charges in Washington state but refuses to meet with police who are continuing to investigate Susan Powell's murder.
Police say he is part of the ongoing investigation.
"Absolutely," West Valley police Chief Buzz Nielson told reporters in Washington. "He's part of the people we talk to that we had some interest in."
Police in both West Valley and Washington say this part of the investigation is necessary despite the fact that Josh Powell and his two boys are dead.
"Well some body's got to speak for the kids," says Sgt. Ed Troyer of the Pierce County sheriff's office. "I mean it's going to be in the memory of a lot of people for a long time and Susan's still missing."
In Utah, police say tips are coming in that could help with the investigaiton.
Robin Snyder claims she recently met with police. She claims she saw Josh Powell and his two sons the day after Susan went missing in 2009.
Back then, Snyder says she at a Sandy hotel where she was in charge of overseeing the free breakfast for guests.
At the time she had no idea who Powell was or that anyone was looking for him.
"I was standing right behind Charlie," Snyder says. "And Charlie looked right up at me and he says 'do you know what happened to my mom?' so I say 'no what happened to your mom?'"
Before getting an answer Snyder was called to the kitchen.
When she came back she says they were gone.
Snyder says she recognized Powell a couple of days later in the news and called police. She says they never returned her call.
But she admits when she left information on the tip line she didn't get into details about what she is now saying.
A spokesman for West Valley police, Sgt. Mike Powell says "they've done an incredible job" of returning calls. But could not go into detail about this particular person because of a court order that prevents them from talking openly about the investigation.
And now a Salt Lake woman is telling police she saw Steve and Josh in the Topaz Mountains three-months before Susan went missing in 2009.
It's where police conducted a massive search this summer. There, they uncovered a shallow grave. But police won't won't discuss their findings.
The woman who wants to remain anonymous told ABC 4 News: "they weren't out there looking for crystals. If they were looking for crystals, they left that area."
She says Steven and Josh were not dressed for the outdoors and were in a vehicle that didn't match anything she's seen them drive in news accounts.
"They were not friendly at all," the woman tells ABC 4 News. "It was obvious they had their agenda and everyone else be damned. Their behavior was so out of the ordinary."
