Best of Crime Exposé with Nancy O'Dell

Time can bury evidence, but it can also reveal the truth.

Some killers never intend to pull the trigger themselves. A pregnant mother is targeted in a plot designed to collect her life insurance. A young wife's murder exposes a conspiracy driven by a family determined to destroy her marriage.

For some killers, murder is a final act of vengeance. A mother becomes the target of an ex-husband consumed by a bitter custody battle. A rejected man's anger turns deadly on an isolated trail.

Family, sometimes, it's the shelter from the storm; sometimes, it's the storm itself.

Nothing is what it seems when killers build their crimes around a lie.

Murderers can destroy evidence, invent stories, even impersonate the dead - but their digital footprints remain.
