Since he has prior DUII convictions, he's lucky he committed this homicide in Lame County, OR instead of Orange County, CA. Down in SoCal, several DAs are requiring intoxicated motorists to sign declarations that guarantee a conviction for second degree murder if they ever kill someone while driving while intoxicated. Failure to sign the document gets them lengthly jail time, so everyone signs. 

Instead of six years, this killer would be doing 25 to life. Or, just maybe, he would have decided that the risk was just too great and would have taken steps to not drive while impaired. Something as simple as living closer to where he works would have saved a lot of grief, even if he couldn't resist the drugs.

Now, if only we had a functioning District Attorney's office. A guy can dream, can't he?
