SAN DIEGO -- After a driver high on methamphetamines killed their father, a brother and sister are out to make sure those driving impaired know the consequences, 10News reported.

On Jan. 25, 2006, Dean Osuna was high on meth and driving down Highway 78 when he crossed the median and killed 48-year-old Derek Ritter.

"I miss his smile, I miss his guidance, I miss his inspiration, his love," said Ritter's son, Kevin.

"I know he's watching. I know he's proud of us. It's what he would have wanted," said Ritter's daughter, Kara.

Since then, Ritter's children have been fighting to not only keep impaired drivers off the road but to make sure those who give them the keys are held responsible.

"Everybody in society has a role to be responsible, and if you make an irresponsible decision you need to be held accountable," said Kara Ritter.

Osuna spent time in jail, but now a jury said Osuna and his girlfriend, who gave him the keys to drive, owe Ritter's family $1.8 million.

The family's lawyer is calling the decision precedent-setting, since the drive and his enabler are being held responsible.

"I think it's a decision that carries with it a very strong message to everybody," said attorney William Berman.

Though they might never see a dime, as Osuna and his girlfriend have no insurance and little money, Ritter's children said their dad would be proud.

"I hope you make the decision to change, and in the future I hope you don't make that decision again. You stop yourself, and you prevent this pain from filtering through any other person's family," said Kara Ritter.

The jury divided the responsibility but not evenly.

They said the driver was 60 percent responsible for the crash, and his girlfriend was 40 percent responsible, even though she was not high or driving but had given him the keys.
