The husband of missing Utah mom Susan Powell is reportedly planning to sell his house and relocate his children to Washington, Fox13Now.com reported.

Joshua Powell is the only person police are calling of interest in his wife's disappearance. Susan Powell’s family said he is planning to sell the house after spending the holidays with his family in Washington state, Fox13 reported.

Powell was reportedly spotted pulling out of his Utah driveway at 3 p.m. local time Wednesday.

Tim Peterson, Susan Powell’s friend, knocked on the front door of the Powell house and shouted out for Joshua Powell. He was at the house to take back a playground set he had given to the Powell family, Fox13 reported.

"He doesn't want to talk about his wife, and you know, the whole world wants to know where his wife is," Peterson said, Fox13 reported. "And, uh, ask him, because you know, in my opinion, only he and God knows."

Utah police have said that Joshua Powell has not been cooperating with them throughout the investigation, Fox13 reported.

Powell, 28, was last seen on Dec. 7, when her husband says he left their suburban home in West Valley City at about 12:30 a.m. to take their two boys, ages 2 and 4, camping in freezing conditions. Police have named her husband as a "person of interest" in their investigation.
