Apparently got in trouble for evading arrest prior to the school year starting back down in Texas. Bonded out but was due for sentencing at a later date, judge set court date for a month or so ago and he didn't show, so an automatic warrant is issued when someone doesn't appear. As others mentioned, they weren't out hunting for him, but when he got pulled over for speeding it popped up and Lancaster County asked if they wanted him. Answer was obviously yes.
Well that makes more sense, but the posted article left that out.
