SAN DIEGO -- A driver who struck a former Navy captain's car and left him bound to a wheelchair was sentenced Friday to six months in jail -- a punishment the family said is hardly enough.

Former Navy Capt. Jack Kriz was driving his Toyota Prius home from Home Depot when he was struck by Nicholas Griffith's pickup truck. The crash left Kriz with liver, respiratory and kidney failure and a traumatic brain injury that required 10 months of rehabilitation.

Sitting in the back of the courtroom in a wheelchair, the once-active Kriz spoke of the activities he can no longer do.

"Snowboarding with my daughter, supporting my son in Special Olympics, surfing on the weekends," said Kriz.

In his only show of emotion during the entire sentencing, defendant Nicholas Griffith looked visibly upset as Kriz spoke of the hardship he's endured since Griffith's pickup collided head-on with his Prius two years ago. Griffith was driving with a suspended license for a prior DUI offense.

On Friday, Griffith was sentenced to six months in jail, 400 hours of community service at a brain injury institute and three years probation.

"I hope the justice system gets through to him ... [and] he can realize the impact of what he did," said Kriz.

Kriz's wife Kathy was hoping for a stronger sentence and wanted Griffith to serve closer to the 886 hours of therapy her husband has undergone.

"It doesn't seem fair. The six months in jail is not even a drop in the bucket compared to how he's affected our lives," said Kathy Kriz.

Kriz's family said their father's strength of will and outstanding physical condition for kept him alive that day. Even the judge called Jack Kriz "admirable" and said he showed incredible strength of character for the compassion he showed to the man who left him disabled for life.

"If you or I should ever make a mistake ... they should be forgiven, but they should not be forgotten," said Jack Kriz.

Kriz's family said the Scripps Ranch community helped them through the ordeal, bringing them food, offering a cleaning service and donating 110 pints of blood when Jack Kriz needed it most.
