The husband of a missing Utah woman has been answering questions from police on a daily basis and is not hindering an investigation into her disappearance, as police have alleged, his attorney said Tuesday.

Scott Williams told The Associated Press that he and Josh Powell met with West Valley City police on Tuesday. He said Powell is answering police questions in an effort to help find his 28-year-old wife, Susan.

Susan Powell was reported missing Dec. 7 when she didn't show up to work and her children weren't dropped off at day care.

Josh Powell told police he took his two boys, ages 2 and 4, camping around 12:30 a.m. that day and returned in the evening.

Investigators said they haven't been able to verify the camping trip because snow had covered the site _ Simpson Springs on the historic Pony Express Trail in Utah's west desert.

The Powell home was locked when police arrived and they broke in, fearing the family had suffered from carbon monoxide poisoning. They found no signs of forced entry.

Susan Powell's father, Charles Cox, has said police found a wet spot in the house being dried by two fans when they entered.

West Valley City Police Capt. Tom McLachlan declined to comment on that, but said earlier Tuesday that Josh Powell was costing the police valuable time because he failed to show up for an interview on Monday.

"We are very disappointed in that because he is not a suspect and this delays the investigation _ it slows things down," McLachlan said early Tuesday. "His stated purpose is he wants to find Susan and that is also our stated purpose on this missing persons case, and this complicates the issue."

McLachlan said police initially interviewed Josh Powell when he returned home and then again the next day. Police have also interviewed the Powells' older son.

Williams said the Monday interview was canceled at his request.

"We have been in contact with West Valley City police multiple times daily," he said. "The Monday afternoon possible interview was canceled by me that morning because I was new and because I needed more information to provide effective consultation and advice."

Williams is a Salt Lake City defense attorney who often represents high-profile defendants in criminal cases. He declined to specify exactly when he was retained by Josh Powell.

McLachlan said late Tuesday that he wasn't aware if police had met with Josh Powell on Tuesday.

"I'm going to have to wait to the morning to get briefed until I can make any statement," he said.
