S3·E14 Neither Rain Nor Sleet

After postal worker Rosie Diaz goes missing during what seemed to be a regular workday, the team initially connects her disappearance to her cargo, which include $12,000 worth of the game Demon Storm, which all the kids were after. But when the team gets in touch with child protective services, they learn that Rosie recently had her foster children taken away after an anonymous abuse call. A search of her home uncovers a DVD containing child pornography, and the team starts to look at the case from another angle. Danny comments on Martin and Sam's obvious closeness, and wonders why they're keeping it quiet.
