263 A.3d 1049
D.C.2021Background
- Defendant Jerome Lewis lived in the basement of a multi‑family house; on Feb. 16–17, 2013 a fire began in his basement, traveled up the stairwell, and a 4‑year‑old (S.M.J.) later died of smoke inhalation.
- Witnesses and surveillance placed Lewis in and around the basement in the early morning hours; after the fire he appeared calm, watched the house burn, threatened family members, and was found with a half‑used book of matches; receipts showed he bought cigarettes that night.
- ATF investigator Lee McCarthy tested ignition scenarios (about 1,100 cigarette/mattress/bedding experiments) using Sealy Posturepedic mattresses and various bedding materials/configurations; mattresses ignited in 20 tests, with flaming combustion averaging 12 minutes.
- McCarthy concluded the fire originated on Lewis’s mattress and was incendiary (either a cigarette that an aware person deliberately allowed to burn or an open flame held to bedding), reasoning that a dropped cigarette accident would likely have been extinguished earlier.
- Lewis was convicted at retrial of first‑degree felony murder (based on first‑degree cruelty to children), first‑degree cruelty to children, and second‑degree murder (lesser included); he appealed, principally challenging the admissibility/reliability of McCarthy’s expert testimony, a requested negligence instruction, sufficiency of the evidence, and the denial of a new trial.
Issues
| Issue | Plaintiff's Argument (Lewis) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Pretrial Daubert hearing and admissibility of McCarthy’s expert testimony under Rule 702 | Trial court abused discretion by denying a pretrial Daubert hearing and admitting unreliable expert evidence | Trial court had sufficient record (prior trial transcript) to assess reliability; denial of separate hearing was within discretion | Denied — no abuse of discretion; court could rely on prior transcript and did not need a separate hearing |
| Reliability/application of experiments to case facts (Rule 702(d)) | Tests were not substantially similar to the unknown, specific bedding/conditions in Lewis’s basement, so methods weren’t reliably applied | McCarthy tested a reasonable range (cotton/synthetic/blends, configurations, airflow) based on available evidence; dissimilarities were non‑material and for cross‑examination | Denied — experiments were sufficiently similar and reliably applied; remaining differences went to weight, not admissibility |
| Relevance/probative value vs. unfair prejudice and opinion on intent (Rule 403 / Rule 704(b)) | Experiments were minimally probative and unduly prejudicial; expert improperly opined on ultimate issue of intent | Experiments bore on whether the fire was incendiary (a contested element); local law permits experts to opine on ultimate issues; no unfair prejudice shown | Denied — experiments were relevant and not unfairly prejudicial; allowing opinion that fire was incendiary did not plainly err under local law |
| Request for civil negligence instruction | Court should instruct jury on civil negligence definition to distinguish negligence from recklessness/intent | Criminal instructions already required proof beyond negligence (intent or conscious disregard); a separate negligence instruction would confuse jury | Denied — no abuse of discretion; instructions as given sufficiently required more than negligence and a civil negligence instruction would be unnecessary/misleading |
