How have the courts treated evidence of bad faith destruction of exculpatory evidence on appeal?

On appeal, the defendant asserts she demonstrated bad faith destruction of exculpatory evidence. We disagree. At most, the officers did not preserve some trash bags and some feed bowls. As the trial court noted, these, alone, were not exculpatory. The presence of trash and feed bags and feed and water bowls does not demonstrate the defendant was not guilty of animal cruelty. Furthermore, there was no indication the officers denied their existence. Accordingly, evidence could still be presented to the jury concerning the existence of this evidence. The officers did not fail to preserve evidence "that might be expected to play a significant role in the suspect's defense." (California v. Trombetta, supra, 467 U.S. at p. 488.)
