‘CSI’ Goes Under Quarantine In ‘Bad Blood’

A potential viral outbreak puts the lives of two CSIs at risk, in the third episode of CSI: Crime Scene Investigation’s upcoming fifteenth season. (Major spoilers after the jump!)

According to CSI Files sources, “Bad Blood” opens with Sara and Greg arriving at a crime scene. There’s blood all over the living room, spattered on the dingy curtains and pooled on the floor. The body of a scruffy man is lying in the largest pool of blood, but the team doesn’t know who he is. He pays cash for the rent, and he uses a fake name. There’s a single bullet wound in the man’s neck, with a corresponding shell casing on the floor. He bled out, but that doesn’t explain the blood spatter and smaller pools around the room; this evidence suggests a struggle, and the team hopes the killer might have left some blood behind too.

As Sara leans down to get photos of the victim’s body, she spots something frightening: the eye closest to the floor is open and bright red, and there are lines of dried blood trailing from his eye, nose and mouth. The man was sick. She alerts Greg, who immediately realizes the danger they’re in. Sara calls the CDC while Greg looks around at the blood coating the room. The pathogen could be in the blood—or worse, in the air they’re currently breathing. When the call goes through, Sara tells the person on the other end that they are dealing with a possible hemorrhagic fever. There’s one known victim—and two CSIs who are potentially exposed.

The house becomes a hive of activity as the CDC arrives to contain the crime scene and transport Sara and Greg to hospital quarantine. Protocol includes using UV light and formaldehyde fog to kill every living organism in the house. This should prevent further infection, but it will also destroy the blood evidence they need to catch their killer. Sara and Greg were able to upload their crime scene photos to the cloud before they were forced to abandon their gear, but that may be all they can save. The team needs to work together to identify the victim, diagnose his illness, and locate his killer before the disease can spread and claim more victims.
