Robert Cooke’s 19-year-old daughter Rachel went missing almost two years ago, and Robert hasn’t stopped in his relentless search for her.

On Jan. 10 2002, Rachel Cooke was last seen jogging near her parent’s house in Georgetown on a Thursday morning while home from college.

Family and friends of the community poured out for support to help search for Rachel in the weeks following her disappearance.

The missing posters were placed around town, commercials were made and a $50,000 reward was offered to anyone who had credible information.

Today, the posters are still around town.

Kathleen Greene, a receptionist at a local clinic, was one of countless volunteers who looked for Rachel.

"We heard about it on the TV, and we helped because our daughter is about the same age. It was our community and we just wanted to be a part of that," Greene said.

Other signs of support are very visible in Georgetown and that keeps the Cooke family pressing on for Rachel’s return.

"I try to keep Rachel in the news and do some things because I know that somebody knows something and that's my goal, is to try and get that person to talk," Robert said.

Robert’s mission to find Rachel is admirable. He organized charity/awareness runs and an alert system similar to the Amber Alert, but for a person of any age.

In April 2002, three months after Rachel's disappearance, Robert helped organize a Run-Walk for Rachel that brought awareness to her case and the impact a missing person has on other families.

In July 2002, Williamson County adopted the Rachel Alert, which allows information to go out at a moment's notice to police and the media about a missing person.

Then, and now, he believes it is just as needed as the Amber Alert for younger people.

"To me there's no reason why a high school senior should start out the year and be eligible to have an Amber Alert issued and by the time they graduate, they're not eligible for that," Robert said.

Robert is also a lobbyist for missing and exploited children. He has met with state lawmakers and taken two trips to Washington, D.C.

Lately, he has also organized free self-defense classes for women, called MUST (Mentally Useful Safety Techniques).

"A lot of times I see mothers -- they're so protective about their children -- so they don't take the time to protect themselves. They need to ask themselves, what would happen to their children if THEY disappeared," Robert said.

As each day goes by, a numbing uncertainty continues to hang over Robert. He stays strong for Rachel.

"And I know the odds are less than one percent that we'll ever see Rachel alive … I said at the very beginning that I wasn't going to sit in a chair and cry all day because I knew that wasn't going to help my daughter … and we just try to keep going, and hopefully, some day it will come through. And we've helped some other people along the way, and that's a good thing too," he said.

Rachel's 21th birthday has come and gone. Her 22nd birthday is in May. Robert will no doubt pause again to celebrate his daughter’s life, which shines as his inspiration to help others also searching for answers.
