At what point does a criminal stop looking over his shoulder and figure he got away with his crime? One year afterward? Five years? Ten years?
The arrests last week for the 1995 murder of Christine Foster and the 1989 murder of Nicole Willis perhaps will convince criminals that the correct answer is "never."
Law enforcement continues to actively work cold cases, aided by new technology and DNA testing. The success at making arrests in these two cases will likely inspire the police to dig even harder into other cold cases.
The families of Christine Foster and Nicole Willis have waited many years for arrests and now will have to wait for trials and they hope guilty verdicts. But justice delayed is still justice.
