Friends and family of Susan Powell launched a three-day social media blitz on Monday to help find the missing Utah mother of two who disappeared almost a month ago.

Friends saturated social networking sites, like Facebook and Twitter, and organized a mass e-mail campaign to spread information about Powell through the Internet, The Salt Lake Tribune 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.

Kiirsi Hellewell, Powell's friend, posted a slideshow with pictures of the missing woman on YouTube and is hoping her disappearance will become a popular topic on Twitter, the Tribune reported.

Organizers said there will also be a purple ribbon campaign to raise awareness of her disappearance and Facebook users are being asked to change their profile pictures to a purple ribbon.

"We're hopping today that by giving everybody so many different options to become involved online that we can actually make this go viral and people can see Susan's face and here about her situation in every corner of the world," family spokeswoman Shelby Gifford said in an interview Monday with Fox News.

Powell's husband, Joshua Powell, reported her as missing on the same day when she failed to show up for her stockbroker job at Wells Fargo and her children were not dropped off at day care.

Police have seized several items from the family's home but have not charged Joshua Powell in connection to the disappearance. Authorities are seeking cell phone records, though police have declined to say whose phone records are being examined, the Tribune reported.

Authorities are also trying to determine where her husband traveled in a rental car two days after his wife was reported missing. He reportedly logged hundreds of miles on the rental vehicle.

Joshua Powell rented the car for 24 hours while police had his minivan in custody to process it for evidence.

Powell has declined to speak again with police and local news crews were reportedly turned away from his father's house over the weekend.

Friends of Powell's told the Deseret News that they have turned over to police e-mails that she sent them last year, in which she reportedly wrote that she feared her husband.

They also said Powell kept a notebook at her work desk that detailed threats allegedly made by her husband in 2008, according to the newspaper.
