A sex offender who failed to register, now sits behind bars, all thanks to a NewsWest 9 viewer.
Raul Rios Junior was picked up on Monday.
Authorities say he changed his address, but failed to register it with the state.
Odessa police found him, thanks to a viewer that saw his picture on our Spin Zone a couple of months ago.
No bond was set.
Authorities also slapped Rios with extra charges for failing to pay child support.
