235 A.3d 758
D.C.2020Background
- In November 2015 Onyekachi Osuchukwu was found shot to death; his friend Eugene Burns was present and later became a homicide defendant. Police seized two cell phones from Burns the day after the shooting and OCME performed an autopsy.
- Detective Littlejohn obtained warrants authorizing forensic examination of both phones for “any evidence” related to the murder; the supporting affidavits established probable cause only for limited items (texts between Burns and decedent on Nov. 14, phone call logs, and GPS/location data).
- Forensic extraction (Cellebrite) produced extensive data (multi-thousand-page reports) including internet search queries (e.g., searches about killing a best friend and shot placement), photos of Burns with a handgun, incriminating texts, and social-media material.
- Dr. Terrill Tops (a deputy medical examiner) performed the autopsy and prepared notes, diagrams, photographs, and a signed autopsy report. Chief Medical Examiner Dr. Roger Mitchell, who did not perform or observe the autopsy, testified at trial about the autopsy findings.
- Burns moved to suppress the phone data (Fourth Amendment) and to exclude Mitchell’s testimony insofar as it repeated Dr. Tops’s findings (Confrontation Clause). The trial judge denied both motions; Burns was convicted of first-degree premeditated murder and related offenses. On appeal the D.C. Court of Appeals reversed, finding both constitutional errors prejudicial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Validity & particularity of cell-phone search warrants | Warrants were overbroad and lacked particularity/probable cause for searching entire phone contents; suppression required under Riley and Warrant Clause | Warrant limited to evidence of the murder and affidavit established probable cause; broad search justified to locate evidence/leads | Warrant invalid: affidavit established probable cause only for narrow items (Nov.14 texts, call log time, GPS); warrants authorized an unlimited search and lacked particularity; violated the Fourth Amendment |
| Good-faith exception to exclusionary rule | Suppression required because warrants were facially deficient and affidavits were "bare bones"; officers should have known warrants were invalid | Evidence should be admissible under Leon good-faith exception because a judge issued the warrants | Good-faith exception rejected: affidavit was bare bones and warrants so obviously overbroad that a reasonably well-trained officer would know they were unconstitutional; suppression appropriate |
| Severability of warrant (admit valid parts) | If portions are invalid, sever the warrant and admit evidence tied to valid parts | Sever parts and admit evidence obtained by validly described searches | Severability rejected: warrants did not specifically describe the narrow items for which there was probable cause, so there were no valid, distinguishable portions to save |
| Confrontation Clause — surrogate testimony by Chief Medical Examiner | Testimony relayed the deputy pathologist’s out-of-court, testimonial findings (autopsy report, notes, diagrams) and thus violated Crawford absent opportunity to cross-examine Dr. Tops | Chief relied on autopsy photographs and gave independent opinion; autopsy materials are not categorically testimonial | Held unconstitutional: Mitchell transmitted testimonial hearsay (Tops’s findings) prepared in the context of a homicide investigation; autopsy records were testimonial and admission violated the Sixth Amendment; error not harmless when combined with suppressed phone evidence |
