Most people assume a drug case starts when officers find drugs. In Greenville County, many start with a person instead: someone already facing charges who agrees to give up names in exchange for lighter treatment. That person is a confidential informant, and their word can put an entire investigation in motion months before anyone knocks on your door. Our drug crime attorneys at Eppes & Plumblee have seen how heavily prosecutors lean on informant-driven cases, and how often that weight sits on a thin foundation.
Where Informants Actually Come From
Most informants are not volunteers. They are people who got caught, usually with drugs of their own, and were offered a way to reduce their exposure by working for the police. Local drug units and the South Carolina Law Enforcement Division rely on this pipeline because it produces fast leads. The problem is baked in from the start: the informant has a personal reason to deliver names, whether those names are accurate. Someone facing years in prison has a strong motivation to tell officers what they want to hear.
How a Controlled Buy Is Built
Once an informant is signed up, the standard move is a controlled buy. Officers search the informant, hand over marked cash, set up surveillance, and send them to purchase from the target. Ideally, officers record and watch the buy from start to finish. That transaction then becomes the backbone of a search warrant affidavit or an arrest.
In practice, controlled buys are rarely as clean as the reports suggest. Officers may lose visual contact. The informant may have had drugs on them that the search missed. The recording may be inaudible at the key moment. Each gap is a place to challenge the state’s version.
The Accuser You May Never See
South Carolina and federal courts recognize a government privilege to withhold an informant’s identity. The leading authority is Roviaro v. United States, where the U.S. Supreme Court held that the privilege gives way when disclosure matters to the defense. Whether the informant must be named depends on the informant’s role: a mere tipster is usually protected. In contrast, an informant who set up and participated in the buy is a witness whose identity and credibility the defense may be entitled to test.
Why Informant Reliability Is a Real Fight
When a case rests on an informant, our attorneys closely review the affidavit that justified the search. Did the officer tell the judge anything about the informant’s track record, or assert reliability? Was the buy genuinely observed? Does the informant have prior convictions, pending charges, or a deal that gives them a motive to lie? If the warrant relied on an unreliable informant, the evidence that flowed from it may be subject to a motion to suppress.
If Your Case Started With a Name
When the state’s case begins with an informant rather than physical evidence, the defense has room to work that most people never realize exists. If you were arrested after what looks like a controlled buy or a tip, Eppes & Plumblee can review how the informant was used and whether the state can back up what it claims.
