C. While we recognize the rule that police officers generally have no duty to collect all potential evidence from a crime scene, we conclude that this rule is not absolute. We do not condone shoddy and inadequate police investigation procedures at the expense of a criminal defendant’s right to a fair trial. In some eases, the State’s failure to gather evidence may amount to suppression of material evidence. See Bradley, at 491 (noting that police “might have a duty at some point to seize an item of evidence”); People v. Vigil, 718 P.2d 496, 503 (Colo.1986) (en banc) (<HOLDING>); State v. Powers, 555 So.2d 888, 890
