338 Conn. 108
Conn.2021Background
- Ten‑year‑old victim awakened on Oct. 15, 2014 by an unknown man who sexually assaulted her; she and her mother later saw the man at a window as he fled. Defendant arrested days later; some physical description matched.
- Sexual‑assault kit: three swabs (two vaginal, one posterior fourchette) and a microscope slide with sperm. Forensic analyst Renstrom separated sperm‑rich and epithelial‑rich fractions and found defendant included in a DNA mixture from the vaginal swabs; he was eliminated from the posterior fourchette sample due to insufficient DNA.
- Renstrom testified the expected frequency of inclusion for the mixture was ~1 in 52 million in the African‑American population; Connecticut’s population is ~3.5 million.
- Fingerprints were recovered from a bedroom window but many prints were poorly defined; detectives testified they did not know how long prints had been present; some unrelated prints from a prior case were inadvertently included on a review disc.
- At trial the prosecutor previewed that DNA was central, gave a relatively brief initial summation, and then delivered a more detailed rebuttal focusing on DNA statistics and minimizing the fingerprint evidence; defense counsel attacked DNA reliability and fingerprint absence in his closing but did not object to the DNA statistical argument during rebuttal.
- Jury convicted on multiple counts; Appellate Court affirmed; Connecticut Supreme Court granted certification and affirmed, holding no Sixth Amendment or due process violation and that any imprecision in rebuttal was harmless.
Issues
| Issue | State's Argument | Gonzalez's Argument | Held |
|---|---|---|---|
| Whether prosecutorial choice to reserve substantive evidence for rebuttal violated Sixth Amendment right to present a closing argument | No; prosecutor gave adequate notice of theory (DNA centerpiece) and defense had opportunity to address evidence | Yes; reserving substantive analysis for rebuttal prevented meaningful response to the way state marshaled evidence | Rejected — no Sixth Amendment violation; defense was on notice and had fair opportunity to present responsive theory |
| Whether that structure violated due process / fair trial | No; rebuttal analyzed evidence already in record and did not introduce new facts or theory | Yes; structure prevented meaningful rebuttal and was prejudicial | Rejected — structure not improper under Williams factors and did not deny fair trial |
| Whether prosecutor mischaracterized DNA statistics (uniqueness / probability error) in rebuttal, infringing right to closing | Argument was a reasonable inference from Renstrom’s testimony about rarity of the profile | Misstated probabilistic meaning and implied defendant was the only Connecticut match; defense could not fully respond in rebuttal | Rejected — no Sixth Amendment violation; defense could have and did challenge DNA reliability; failure to object suggested no belief in constitutional harm |
| Whether misstatements about DNA and fingerprint age (and their cumulative effect) deprived defendant of a fair trial | Statements were brief, based on testimony (age unknown), and not severely prejudicial; general jury instructions cured any imprecision | Statements were misleading and, coming in rebuttal, were especially prejudicial | Rejected — even if imprecise, remarks were not frequent/severe; jury instructions and overall strength of evidence rendered any error harmless |
