The Williamson County Sheriff's office has released a sketch of man who may have witnessed what happened to Rachel Cooke.

Cooke disappeared last Thursday after a morning jog near her Georgetown home.

Crews have been combing the area and following leads for a week now.

The man is described as 18 to 25 years old, six feet tall and 180 pounds. He has black hair and a muscular slim build.

He was last seen driving a white small Nissan or Toyota pick up truck. The sheriff's office also says he has an injured hand that would require medical attention.

Anyone with information is asked to please call the Williamson County Sheriff's office at (512) 943-1313 or (512) 943-1312.

In the meantime Cooke’s family has asked a private search firm to help find the missing woman.
