Leo McCarthy gives college scholarships to teenagers who pledge not to drink while they're underage.
In 2007, McCarthy lost his 14-year-old daughter, Mariah, when an underage drunken driver hit her and two of her friends as they walked down a sidewalk near her home in Butte, Montana.
Through McCarthy's nonprofit, Mariah's Challenge, more than 140 teenagers have received $1,000 scholarships.
CNN asked McCarthy for his thoughts on being chosen as one of the top 10 CNN Heroes of 2012.
CNN: What do you hope this recognition will mean for Mariah's Challenge?
McCarthy: It's a very quiet sense of pride for this town. We have such a hard history of living here. ... (We use) the term "Butte tough." Now, it's more about character and strength, about growing old and helping our youth to grow old.
