FORTH WORTH, Texas -- The search is on for the so-called "affluenza" teenager who avoided jail time for a deadly drunk driving accident.
A warrant has been issued for Ethan Couch. Investigators say his parole officer hasn't been able to reach him or his mother for several days.
Couch was 16 when he slammed into a crowd of people in 2013, killing four of them near Fort Worth.
He was given 10 years' probation in December of 2013 after his attorneys argued Couch lived life as a rich kid whose parents gave him no boundaries or consequences.
"I'll always cherish memories that we had," said Eric Boyles, father and husband of two women killed. "Today, those memories are painful because it brings you to the situation that they're not here today."
"He may think he has gotten away with something, but he hasn't gotten away with anything," said Marla Mitchell, mother of a victim.
Instead of the 20-year sentence Texas prosecutors were hoping for, juvenile court Judge Joan Boyd gave Couch probation.
The teen pleaded guilty to intoxication manslaughter. His blood-alcohol level was three times the legal limit, and he was driving almost twice the speed limit when he crashed his dad's Ford pickup into the victims.
"Taking him away from his family and teaching him to be a responsible citizen, that is a consequence," said Scott Brow, Ethan Couch's defense attorney.
Couch checked into a half-a-million dollar rehab program in California when he was sentenced. Dad and mom foot the bill. He was not allowed to see them for two years.
The victims' families argued they'll never see the loved ones he took away.
"My wife and daughter are gone, and there's no consequences to the individual to which that occurred," Boyles said.
The crash also left two people severely injured.
"My immediate reaction is I'm back to week one. We have accomplished nothing here. My healing process is out the window," Boyles said.
The crash happened on June 15 on a rural road in Fort Worth.
