Enter the room.
A faint stench wafted from the living room.

They were laden with dust.

Because odors are sometimes part of the crime scene, unless dealing with a corpse that was clearly contagious, veteran detectives and forensic investigators wouldn't usually bother to wear masks.
Ivan frowned, sniffing around: "This smell doesn't seem like a decomposing body."

The male in question seemed to have some issues, his urine smelled somewhat fishy...
Excrement carries unique biological pheromones.
