Jan. 4, 2010— -- The family of the missing Utah mother has launched a public relations blitz on social networking sites with the hopes someone has additional clues after nearly a month with no word from Susan Powell.

"We're hopeful somebody will be able to remember something or something will strike them," family spokeswoman Shelby Gifford told "Good Morning America."

The family is posting new videos and pictures on Facebook, Twitter and YouTube, hoping to add to the dozens of new leads West Valley City police say they've been getting each day. As of this morning, the Facebook page dedicated to the search for Susan Powell had more than 14,200 members.

Susan Powell has been missing since Dec. 6, the day her husband Joshua Powell packed up the couple's young sons for a middle-of-the-night camping trip in below-freezing temperatures. It was a trip, her famiy has since said, that Susan Powell would have never allowed.

Joshua Powell was named a person of interest by police, who have claimed he hampered the investigation by refusing to answer several questions. He hired noted Salt Lake City criminal defense attorney Scott Williams as attention turned on him.

Investigators said they have uncovered an e-mail from Susan Powell in which she tells friends that her marriage is troubled.

Susan Powell's father, Chuck Cox, told "Good Morning America" today that his son-in law has said little in recent weeks as he brings the boys, ages 4 and 3, to visit.

"We've only had a few words each time as he's dropped the kids off or picked the kids up and he's had nothing to say at all about where Susan might be," Cox said. "He told me a couple weeks ago that he didn't know where she was and there's been no change."
