HB 840 -- Evidence of Hazardous Materials Sponsor: Pearce Currently, when hazardous material is seized at a crime scene, the seizing officer may take a representative sample of the material for evidence purposes and dispose of the rest of the material as safety concerns warrant. This bill allows law enforcement officers to use photos or videotape of hazardous materials being seized at the crime scene, rather than submitting a representative sample of the material, as evidence of the material.Copyright (c) Missouri House of Representatives
