The reward for a 47-year-old San Antonio woman has increased to $10,000.
Michele Boyd's loved ones said a family friend donated to the award amount.
Boyd was reported as missing on Thanksgiving Day.
Police found her car on Rigsby Avenue, 30 miles away from her northwest-side home. Her Identification card, social security card, and credit cards were all still in the car, police said.
Her family says the wife, mother, and nurse could be suffering from mental illness and may not even know her real name.
They believe she could be in the San Antonio area, San Francisco, or Florida.
The $10,000 reward will go to anyone that can provide a solid lead on her finding.
