A Hamilton County sheriff’s deputy Friday will crash a car to raise money for his children’s school.

“I’m gonna have the pedal down. I don’t care who I hit or what I hit,” said Brad Osswald, 43, Arcadia, whose entry into the county 4-H Fair’s first demolition derby will help fund Hamilton Heights High School’s locker room expansion.

Osswald won’t be driving his squad car, but a 1986 Chevrolet Impala station wagon he calls The Dawg Wagon. He borrowed the car, fittingly already painted in the school colors of orange and black, from Tyler Padgett, Noblesville.

Osswald is selling personalized paw prints on the car for $20 each. The money will go toward lighting, air conditioning, heating and drywall for the new locker room.

“If I can raise $500, that’s awesome. If it’s more, that’s great,” said Osswald, a school district resource officer whose oldest son, Jordan, plays football for Hamilton Heights.

The $250,000 locker room expansion will benefit The Husky Champion Club, a nonprofit group formed nearly four years ago to raise money for the high school athletic department’s capital projects.

Club president Devon Sherer, 53, Cicero, said about 75 percent of the funds already have been raised. The 5,000-square-foot expansion includes lockers, training and meeting rooms, coach’s office, officials room and laundry room.

“We hope to finish it by football season,” said Sherer, whose son Tyler is the Huskies’ quarterback.

It’s the first time a demolition derby — top prize is $1,000 — has come to the county 4-H Fair, which opens today and continues through Monday at the 4-H Fairgrounds, 2003 E. Pleasant St.

It’s Brad Osswald’s first time to compete in a demolition derby, a motorsport in which contestants crash old cars into each other, with the last vehicle surviving being the winner.

“It’s a way to have fun and help the kids,” said Osswald, whose four children, Jordan, 16, Jared, 13, Janae, 9, and Jillian, piled into the back of the car Monday night. They held on as their dad spun doughnuts in the backyard of the family’s 6-acre farm.
