Case (cite)
People v. Ornelas-Licano, 2020 WL 1802798 (Colo. App. 2020)
In sum, the Colorado Supreme Court has consistently required more than the expert’s own assertions to support the required finding that the expert’s underlying theory is reliable. That showing was not made in this case.
The court found the error was not harmless: Moreover, “[t]here are special concerns attendant to law enforcement expert testimony.” . . . For example, “there is something qualitatively different about law enforcement expertise from other forms of expertise” because “[l]aw enforcement officers … are experts in whodunit, and there is a danger that a jury will perceive their area of expertise as solving crimes and determining guilt or innocence.”
