strange times around the loft building in downtown salt lake. so shocking that one of their own chris wright had been arrested and charged with killing wealthy businessman ken dolezsar. >> all the evidence that we obtained led up to chris wright being the triggerman. >> reporter: in the suv ken drove to his fatal morning meeting, for example. the killer used that vehicle to flee the scene. and when the cops found it and scoured the interior, they got a hit. chris' dna. >> we had a dna result from the inside door handle of the suv. >> reporter: it was a tiny sample, not a perfect one, but it seemed to put chris in ken dolezsar's car driver's side which certainly helped the case. but it wasn't quite air tight, not yet. the murder weapon had not been found.
