A missing woman's daughter helped coordinate a self-defense class.

KANSAS CITY, MO.  --  Two years after she vanished it is still unknown what happened to Summer Shipp.  The Kansas City woman disappeared in December 2004 while doing door-to-door research in Independence.

On Saturday's tragic anniversary, friends and family were working to keep others safe. 

Shipp's daughter Brandy teamed up with the Achieve Foundation to help others learn how to defend themselves.

"We don't know what happened to my mother, self defense possibly could have saved her from what happened," Brandy said. "We don't know the details so we don't know but it can't hurt to know self defense."

Brandy learned self-defense moves right along with everyone else and she said that one life saved makes this all worthwhile.

"I'm gonna continue my search and I'm still as focused and dedicated today as I was two years ago in finding answers and finding out what happened to my mother and finding the person responsible and I think it's just a matter of time justice will prevail," she said.

The free self defense workshops continue until Sunday from 8 a.m. to 1 p.m. at the Screenland Theatre at 17th and Washington in Kansas City, Missouri.
