Williams v. State, 141 A.3d 1019

Wayne Williams was indicted on drug-dealing and related charges after police found cocaine and marijuana in his possession following a traffic stop; he admitted selling drugs and attempted to ingest a baggie during arrest.
Police weighed the seized drugs at Troop 4 (6.6 g cocaine; 17.7 g marijuana); later testing at NMS Labs showed lower weights (4.10 g cocaine; 14.35 g marijuana).
Between seizure and testing the evidence was transferred to the Office of the Chief Medical Examiner (OCME) evidence vault; contemporaneous investigations revealed misconduct at the OCME and missing/stolen drug evidence in other cases.
The trial court excluded broad inquiry into OCME misconduct, permitting cross-examination only on tampering, weight discrepancies, and chain-of-custody errors; the court found no evidence the envelopes were opened at the OCME.
Jury convicted Williams of drug-dealing and related counts (the State conceded the Tampering with Physical Evidence conviction must be reversed under precedent); Williams appealed alleging a Confrontation Clause violation by limiting cross-examination about OCME misconduct.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether limiting cross-examination about OCME misconduct violated Williams’ confrontation rights	Williams: OCME misconduct was relevant as an alternative explanation for weight discrepancies and impeached evidence integrity	State: Envelopes were never opened at OCME; permitting broad inquiry would invite speculation and confuse jury	Limitation was reasonable; no Confrontation Clause violation (trial court did not abuse discretion)
Admissibility/chain of custody given OCME involvement and report errors	Williams: chain problems and OCME misconduct undermined reliability of drug evidence	State: continuous handling testimony established sufficient chain; NMS chemist found seals intact and identified substances	Chain of custody was adequate to admit evidence; weight discrepancy addressed at trial
Whether any constitutional error was harmless	Williams: exclusion of OCME misconduct evidence could have affected jurors’ assessment of evidence weight	State: overwhelming untainted evidence (admissions, conduct at arrest, physical evidence) supported convictions	Even if error, it was harmless beyond a reasonable doubt given admissions and other strong proof
Whether Tampering with Physical Evidence conviction stands	State conceded and cited precedent	Williams: challenged applicability of tampering statute where police immediately retrieved the bag	Court reversed Tampering conviction and remanded for resentencing (sentence depended on that count)
