Lana Canen v. Dennis Chapman
847 F.3d 407
7th Cir.2017Background
- In 2002 Helen Sailor was murdered; latent fingerprints from the scene were sent to Detective Dennis Chapman, who identified a latent print on a medication container as belonging to Lana Canen.\
- Canen was tried (2005), convicted of felony murder, and sentenced to 55 years; defense reviewed the prosecutor’s file and retained a retired detective who found only limited similarity but did not depose Chapman or challenge his qualifications at trial.\
- Chapman testified at trial about his fingerprint experience (including FBI training and prior comparisons) but did not disclose that his training was primarily with known (inked/digital) prints and that he lacked formal latent-print examiner qualifications.\
- After exhausting direct appeal, Canen obtained postconviction relief in 2012: a latent-print expert and the Indiana State Police excluded Canen as the source; Chapman recanted his trial identification and admitted limited latent-print experience. The state court vacated the conviction and Canen was released after over seven years in custody.\
- Canen sued Chapman under 42 U.S.C. § 1983 alleging a Brady-based due process violation for failing to disclose his lack of latent-print qualifications; the district court granted summary judgment for Chapman on qualified and absolute immunity grounds.\
- The Seventh Circuit affirmed: it held (1) Chapman was entitled to qualified immunity because no clearly established law required an officer in his position to affirmatively disclose limited latent-print training, and (2) Chapman enjoyed absolute witness immunity for the preparation and presentation of his trial testimony.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Chapman violated Brady by not disclosing lack of latent-print qualifications | Canen: Chapman misrepresented his expertise and suppressed material evidence (Brady) that would have impeached or avoided her conviction | Chapman: He did not suppress clearly exculpatory evidence; his testimony was admissible and defense had means to probe qualifications | Court: No clearly established Brady right requiring an officer to volunteer limited training; qualified immunity applies |
| Whether existing precedent clearly established the right (qualified immunity second prong) | Canen: Newsome and other Brady/impeachment cases show officers cannot withhold fingerprint-related exculpatory or impeachment evidence | Chapman: Those cases differ (clear exculpatory or affirmative disability/misconduct); Indiana law permits expert testimony based on practical experience | Court: Precedent not sufficiently particularized or analogous; right was not clearly established |
| Whether testimony/preparation is protected (absolute immunity) | Canen: Claims partly attack testimony and preparation — not shielded if testimony false or prepared to mislead | Chapman: Witnesses (and their preparation) have absolute immunity for courtroom testimony | Court: Absolute immunity bars civil liability for preparation and presentation of testimony (absent extreme misconduct beyond testimony) |
| Admissibility and materiality of omitted qualification under state evidentiary law | Canen: Omitted qualification was material impeachment evidence bearing on guilt | Chapman: Under Indiana Rule 702 and case law, practical experience can qualify a witness; lack of formal latent training goes to weight, not admissibility | Court: Under Indiana law Chapman was admissible as an expert; omission did not create a clearly established constitutional violation |
