The family of a missing Atlanta woman is searching for answers as they try and figure out why a 31-year-old vegan blogger disappeared four days ago.

Victoria Moon Erickson was on a road trip across the country, blogging about vegan cuisine and healthier lifestyles.

WSB Radio spoke with Erickson's sister, Kat Erickson, on Friday who says, "She left to go to our family's mountain house on Dec. 21st, and I know that it was on her agenda to hit Missouri and then she ended up in Texas."

Erickson was last seen in Houston at a well-known restaurant that is a source for fresh raw vegan cuisine.

The owner of Pat Greer's Kitchen, located on West Clay, is one of the last people to talk to Vicky.

"I've been in communication with Pat Greer.  She is really a great woman and has been helping a lot to put together the pieces here, what we can about what happened to Vicky in the last days and hours that people saw her," says Kat Erickson.

Greer recently offered Vicky a job to work in her vegan kitchen and a room to stay in.

Victoria was last seen on Monday, January 21, 2013.

"She left behind pretty much it appears all of her belongings, like a bag of clothes, keys, cell phone, wallet with ID, her dog, which she's very responsible with her dogs," says Kat Erickson.

Houston police have filed a missing person report for Victoria Moon Erickson.

On Friday detectives issued a flier with photos of the vegan blogger to Houston area jails and hospitals.
