up to 15 years in prison for a charge of driving under the influence with serious injury. the charge stems from an accident he had earlier in the year shortly after he returned from his last deployment. while conrad has pled not guilty, he admits he was drinking on the night of the accident. >> going out, that's one of the things the military preached. when you go out, you have a plan, have a plan. that was what i was going to do. i was going to call a cab and get home. why i decided to get back in the car, i couldn't even begin to friggin' say why. i ended up crossing the center line and hit someone head on. the individual i ended up hitting, she had a broken leg and multiple injuries thing. the dui, i could have handled that. the wrecking the car, i could have handled that. hurting someone, that's what sucks the worst. >> conrad is negotiating a plea deal that he hopes reduces his prison time to no more than three years plus probation. the deal would include oversight from a veteran's court which will include treatment for post-traumatic stress disorder.
