BOISE -- 9-year-old Kembrie Souza is proving that you can make a difference, no matter how old you are. She's been raising money for Mothers Against Drunk Driving (MADD), and so far, she's raised more than $2,500 in honor of her cousin, Aimee, who was killed by a drunk driver back in 2005.

Kembrie, who was only one at the time doesn't remember Aimee, but she lives on through her pictures and through family memories.

They told me she liked to hold me and she was really nice, said Kembrie. Aimee Souza would be in her 20s now and Kembrie says she wishes she had her in her life.

Kembrie's Mom, Kara, fought for justice for Aimee when the drunk driver who killed her got in trouble with the law yet again.

He got a second DUI, and I fought for tougher sentencing on that 2nd DUI, said Kara. It's just been an emotional roller coaster that doesn't end.

Representatives from MADD assisted Kara with her push for tougher sentencing. Then when Kembrie was deciding on a service project for school, she went with a fundraiser for MADD so that she could give back to the organization that helped her mom so much.

With a goal of $500, Kembrie decided to organize a yard sale at her church. She asked for donations, and made signs.

The yard sale was a huge success, and Kembrie raised far more than she expected -- a total of $2,508, so far.

This month, at the Walk Like MADD 5K in Boise, Kembrie was honored for having the top team, and being the overall top walker.

It was really exciting, she said. I think they were proud of me.

She's only 9, and I don't think she realizes the impact that she's having and the amount of money she raised, said Kara.

Kembrie says she plans to keep on making a difference. She'll Walk Like MADD to honor Aimee again next year.
