this audio from the sheriff's office? explain the significance of it. >> reporter: well, anderson, this all goes back to that august 12th 9-1-1 call when someone called saying they had seen a man slapping a woman this is key because this is the dispatch tape to the moab police officers telling them that a male was seen slapping a female. that's what they said on that audio. so this was key because then the moab police were dispatched to find the couple. they found gabby petito and her fiance. they turned on their body camera and on that body cam, you see gabby petito visibly upset. she is crying. brian laundrie is showing them scratches on his hands. she says they did have a fight but she does tell the officers that he did not punch her. so they told them to separate for the night which they did but now we have learned that there is this investigation by the city of moab into the handling of this call because we know, also, that gabby petito was dead within about two weeks or so of that police stop, anderson. >> and what is the latest on the search for -- for laundrie? are they still focusing on this
