AUSTIN (KXAN) — It’s been 17 years since she was last seen or heard from, but the FBI has not given up hope of finding Rachel Cooke. 

Williamson County Sherrif Robert Chody tweeted a photo of a billboard that features a photo of the smiling Cooke with the caption “MISSING BUT NOT FORGOTTEN.” A reward of $100,000 is being offered for information in her case. 

Chody’s tweet read: “Thanks to the @FBISanAntonio we were able to put a couple of billboards along I35 to help us #BringRachelHome. Today is Rachel’s 37th birthday. Help us bring Rachel home!” 

In 2002, when Cooke was 19 years old, she went missing while she was on her usual four-mile run while visiting her parents in Georgetown. 

Over the year, Cooke’s family, law enforcement and the community have not given up hope to find out what happened to her.

Most recently, in December, law enforcement conducted a mysterious dig in Georgetown looking for possible clues in connection with Cooke’s disappearance. Officials could not confirm after the dig if anything was found but they then moved on to new leads. 

Anyone with information about her disappearance can provide tips to the FBI at 1-800-CALL-FBI.
