Drive to Tijuana. Park it somewhere. Leave it unlocked. Walk back.
TJ is a little far away from Pullman, WA. I would say drive it to Spokane, give the keys to a bum or illegal.
All evidence would be completely destroyed upon this person using/living in/selling this vehicle. I was pretty sure a few pages ago that they would have a short-stack list of people based on the vehicle, if it was indeed the one they were looking for, they just needed a tip to connect the person to one on the list of registered Elantra owners.
The K-Bar murder weapon is long gone by now, but the fact that they recovered the vehicle is amazing. There should be trace evidence that would link him to the crime scene in it. There's no way you stab 4 people to death and track nothing into your vehicle.
