(WMC- TV) - It has been a week since the disappearance of missing mom Karen Thomas. Her family says they refuse to give up hope.
On day six of the search, the family expanded their search in Raleigh in a wooded area off I-40 near Covington Pike.
Thomas' older sister Renee Shaw, says Thomas recently started a new career in accounting and is very responsible.
"She loved that job and for her not to be there in the morning to get her kids ready for school, that's not like my sister," said Shaw.
Thomas' husband Terrence was the last person to see her alive but has not been present in the search efforts.
Shaw says she went by the couple's home Tuesday and noticed police had been by with a search warrant.
Investigators confirmed with Action News 5 that a search warrant had been executed at Thomas' home in the 2700 block of Welchlawn Cove, but said the finding were not yet available.
Search members posted flyers around the city and now offering a reward for information.
Sley Gwyn offered his expertise in the search as a member of the family and U.S. National Guard.
"If there's not any indication of a body in the vehicle then it could be close by," said Gwyn.
Search members said they were looking for anything that could lead them to Thomas, a shoe, an article of clothing, or anything she would leave behind as a clue.
A candlelight prayer is planned for Friday at 6 p.m. in the parking lot of Garden Ridge on Summer Avenue where he car was discovered Monday.
Thomas is 5'6", 95 pounds, with black hair and brown eyes. She was wearing a dark shirt and blue jeans when she disappeared.
