    Homebodies
    episode S4.E3 october 2003
    Fingerprints suggest a link between two home invasions, but it's hard to link either the victims or the logical suspects, who may all be innocent.

Its place is a mystery, being so overt and unrelated to the victim, a bounty-hunting has-been, until the team consults the sky.
