>> reporter: johnny hott was at a friend's house when he got the news. >> and kind of shook me. and said, "they found them. they've arrested them. they got them. they've caught them." really, though, it wasn't until i watched it on tv and i saw that they apprehended someone that i felt like possibly it was over. >> reporter: it all left those grieving for the harveys with a different kind of sorrow. the murders of two parents and two little girls hadn't been personal at all but rather monstrously impersonal, allegedly committed by two career criminals from out of town. >> the anger that goes along with this, that we actually had someone that invaded our city to prey upon the citizens of richmond. >> reporter: someone who happened onto 31st street. >> as far as we could tell, it was a crime of opportunity. a nice two-story brick house in a nice neighborhood on a nice day, with the front door open.
