Episode 90 of "Without a Trace"
s04e20 More Than This

The team searches for a young blue blood who went missing from the inner city shelter for indigent women where he volunteered as part of his sentence for drug possession. As the agents investigate whether Breck Mulligan was victimized by one of the shelter's resident's abusive husbands, pimps or dealers, they also ponder if Breck, a repeat drug offender, fell back into that dangerous world. Breck's powerful father counters that his reformed son was likely kidnapped in the shelter's dicey neighborhood by someone seeking a hefty ransom. After learning that Breck's father cut him off financially following his arrest, the agents also wonder what Breck did to obtain thousands of dollars from "anonymous donors" to keep the shelter open.
