Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF WISCONSIN

KRISTOPHER PAUL TORGERSON,

Plaintiff, v. OPINION and ORDER

DR. MICHAEL A. STIER and DR. ROBERT F. 26-cv-64-jdp CORLISS,

Defendants.

In response to a screening order, plaintiff Kristopher Paul Torgerson brings an amended complaint, alleging that a forensic pathologist, defendant Dr. Michael A. Stier, gave false testimony in his state criminal prosecution, and that Stier’s supervisor, defendant Dr. Robert F. Corliss, failed to act on complaints about Stier’s performance. Torgerson, who is incarcerated at Stanley Correctional Institution, seeks relief under 42 U.S.C. § 1983. Torgerson is proceeding without counsel. Torgerson proceeds without prepaying the filing fee, so I must screen the amended complaint under 28 U.S.C. § 1915(e)(2)(B) and dismiss any part of it that is frivolous or malicious, fails to state a plausible claim for relief, or seeks money damages from an immune defendant. I must accept Torgerson’s allegations as true and construe them generously, holding the amended complaint to a less stringent standard than one a lawyer drafts. Arnett v. Webster, 658 F.3d 742, 751 (7th Cir. 2011). I will dismiss the amended complaint with prejudice for failure to state a plausible claim for relief, and I will impose a strike pursuant to 28 U.S.C. § 1915(g). ALLEGATIONS OF FACT The allegations of facts are drawn from the amended complaint, as supplemented by the docket sheet in Marathon County case no. 2014CF860. On March 24, 2017, in the ’860

case, a jury convicted Torgerson of first-degree intentional homicide and hiding a corpse. On June 8, 2017, the trial court sentenced Torgerson to life in prison. A. Stier’s involvement in Torgerson’s criminal case Defendant Stier was a professor of forensic pathology at the UW School of Medicine and Public Health. Stier performed forensic autopsies for Wisconsin counties pursuant to contracts between the counties and UW School of Medicine. In September 2014, the Marathon County medical examiner contracted with UW Health for Stier to perform an autopsy of the victim in Torgerson’s criminal case. When Stier

conducted the autopsy, he failed to follow certain procedures established by the National Association of Medical Examiners (NAME) for suspected child abuse cases. Stier’s autopsy report described the victim’s eyes as “sunken without discernible pupillary dimension.” Dkt. 14 ¶ 4. But Stier testified at Torgerson’s trial that the victim’s “eyes were missing.” Id. Six days before Torgerson’s trial, Stier sent thigh tissue samples from the victim to a laboratory. The transfer was not conducted through standard chain of custody procedures, and it was not disclosed to Torgerson or his counsel. B. Complaints about Stier’s conduct before Torgerson’s criminal case

In April 2010, more than four years before Stier’s involvement in Torgerson’s case, the deputy coroner of Dane County, Barry E. Irmen, sent an email in which he raised concerns about Stier’s professional conduct and interactions with prosecutors. Irmen wrote that prosecutors could “somewhat” predict Stier’s “reactions,” and that they were circumventing the medical examiner’s office “to get what they wanted done . . . by an outside pathologist.” Dkt. 14 ¶ 8. Corliss responded that he agreed with Irmen and hoped to avoid similar situations going forward.

The next day, the Rock County coroner, Jenifer L. Kreach, sent a formal complaint to the chair of the UW Department of Pathology and Laboratory Medicine. Keach reported that her staff had expressed concerns about Stier’s moodiness and inappropriate conversations at autopsies, and that law enforcement had described Stier’s conduct as “grossly inappropriate.” Id. ¶ 11. Corliss did not act on any of the complaints that he received about Stier. Nor did Corliss disclose any of the complaints to Torgerson or his defense counsel. In 2022, Torgerson’s spouse, Emma Torgerson, started making public records requests

on his behalf. In 2023, through those requests, Torgerson first discovered the complaints about Stier.

SCREENING THE AMENDED COMPLAINT I take Torgerson to bring Fourteenth Amendment due process claims against Stier based on allegations that he: (1) presented false testimony at Torgerson’s trial; and (2) failed to disclose impeachment evidence. I also take Torgerson to assert the same claims against Corliss based on allegations that he caused Stier to commit that conduct by failing to act on complaints about his performance. Torgerson alleges that the due process deprivations contributed to his

conviction in the ’860 case. See Dkt. 14 at 7–8. Torgerson seeks damages. A. Claim based on false testimony Torgerson’s due process claim based on false testimony has two primary problems. First, this claim is barred by Heck v. Humphrey, 512 U.S. 477 (1994). Heck held that if a plaintiff

“seeks damages in a § 1983 suit, the district court must consider whether a judgment in favor of the plaintiff would necessarily imply the invalidity of his conviction or sentence; if it would, the complaint must be dismissed unless the plaintiff can demonstrate that the conviction or sentence has already been invalidated.” Id. at 487. Torgerson’s allegation that false testimony led to his conviction at least implies that the conviction is invalid. See Moore v. Burge, 771 F.3d 444, 446 (7th Cir. 2014); see also Mack v. City of Chicago, 723 F. App’x 374, 376 (7th Cir. 2018) (“‘Imply’ is not synonymous with ‘invalidate.’”). Second, witnesses enjoy absolute immunity from civil liability based on their trial

testimony. Rehberg v. Paulk, 566 U.S. 356, 367 (2012). Absolute witness immunity bars Torgerson’s due process claim against Stier based on false testimony. Third, Torgerson has not alleged a plausible basis to attribute Stier’s false testimony to Corliss. Torgerson alleges that Corliss failed to act on complaints that he was biased in favor of prosecutors and behaved inappropriately during autopsies. Torgerson does not allege that anyone raised a concern about Stier presenting false testimony at trial. Torgerson’s allegations don’t support even an inference that Corliss’s failure to act on those general complaints contributed to Stier’s presentation of false testimony in his trial seven years later. “This sort of

attenuated theory of causation has no place in § 1983 litigation.” Faulkner v. Litschner, No. 04- cv-408, 2004 WL 1774642, at *4 (W.D. Wis. July 23, 2004). I will not allow Torgerson to proceed on his due process claim based on false testimony. B. Claim based on failure to disclose impeachment evidence The basic rule is that the state violates due process if it fails to disclose material exculpatory or impeaching evidence to the defendant in time for him to use it.
