Across
  1. 3. I store the iron recycled from the crime scene.
  2. 4. I ruptured right inside the vessel — no one caught me in time.
  3. 11. Too much pigment turned the skin yellow — that's me.
  4. 12. I'm the brown pigment that proves the case is really closed.
  5. 13. I'm the fragmented cell — evidence of destruction.
  6. 14. They call me the graveyard of red blood cells.
  7. 16. I'm the yellow pigment left behind after heme breaks down.
  8. 17. I'm the enzyme that rises when cells are stressed or dying.
  9. 18. I'm iron locked away and hidden from harm.
Down
  1. 1. Hemoglobin showed up in the urine sample — I'm the reason.
  2. 2. Too few red blood cells were found at the scene — call it what it is.
  3. 5. I was caught outside the vessels, in the spleen and liver.
  4. 6. I'm the plasma protein that binds free hemoglobin after the crime.
  5. 7. I'm the young red cell, here to replace what's lost.
  6. 8. I'm the scientific name for the victim itself.
  7. 9. I'm the cell that swallowed the evidence whole.
  8. 10. Free hemoglobin was found floating in the blood — that's me.
  9. 15. I turned green before I turned yellow — who am I?
  10. 19. It happened inside the bloodstream itself. That's my alibi.
