tell me why it's important to you that the men who did this are caught. >> i won't have fear in my own home. that they can come and try and finish what they tried to do 21 years ago. >> reporter: casey wian, cnn, new mexico. >> the murders, you've covered this case a lot on "america's most wanted." why does it resonate with you? >> it's a heartbreaking horrible case where two guys break into a bowling alley. there are three or four staff working there. they hold them hostage and in walks a guy who also works at the bowling alley with his two small daughters. and these two creeps, for $4,000, shoot everybody. four of the victims die. the man and his two daughters for a $5,000 robbery. this is something that tore apart this community.
