PORTLAND, Ore. -- A $1,000 reward is being offered for information about a Portland mother who disappeared nearly three weeks ago.

Heather Mallory-Cole, 32, was last seen at her apartment in southeast Portland on March 8.

She attended school and work the previous day and spent the night out with friends. When she returned home, she and her husband were in an argument and Mallory-Cole took off. She hasn’t been seen since then.

Detectives said there’s been no activity on her bank or credit cards and there have been no reported sightings.

Her parents have said her son and her studies were motivating factors in her life and they can’t imagine she would abandon either one.

Mallory-Cole drives a red 2001 Ford Focus with an Oregon license plate of 061 BZX. The car has a bike rack on top and a car seat in the back.

She is described as 5 feet, 5 inches tall, 120 pounds with blond hair and brown eyes.

If you have any information, call 503-823-4357.
