There appears to be a split shaping up between the circuits over the use of a surrogate to introduce autopsy reports. Thanks to federalevidence.com here are the basics.
[Are] autopsy reports are admissible under the Confrontation Clause. The First Circuit has held that autopsy reports may be admitted without the testimony of the report author consistent with the Confrontation Clause. See United States v. Feliz, 467 F.3d 227, 237 (2d Cir. 2006) (autopsy reports as public reports were “not subject to the strictures of the Confrontation Clause”) [Note, case decided before Melendez-Diaz]; United States v. De La Cruz, 514 F.3d 121, 133-34 (1st Cir. 2008) [n.1] (“An autopsy report is made in the ordinary course of business by a medical examiner who is required by law to memorialize what he or she saw and did during an autopsy. An autopsy report thus involves, in principal part, a careful and contemporaneous reporting of a series of steps taken and facts found by a medical examiner during an autopsy. Such a report is, we conclude, in the nature of a business record, and business records are expressly excluded from the reach of Crawford.”), cert. denied, 129 S.Ct. 2858 (2009); see also First Circuit Identifies And Discusses Crawford Confrontation Clause Open Issues.
With that FE provides the case that sets the conflict, and it’s a surrogate case.
